How do you put things out of scientific notation?

If the exponent is positive, move the decimal to the right the same number of spaces as the number of the exponent. If the exponent is negative, move the decimal to the left the same number of spaces as the number of the exponent.Examples:2.5 x 103 is 2500 in standard notation. (Move the decimal to the right 3 spaces.)4.9 x 10-5 is 0.000049 in standard notation. (Move the decimal to the left 5 spaces.)


What should you do when you move a decimal point to the right?

The answer depends on why you move the decimal point to the right. In the context of scientific notation, you increase the exponent by the number of place that the decimal place is moved.


How do you do scientific notation with decimals?

2400 = 2.4 x 10^3 0.0024 = 2.4 x 10^-3 Move the decimal to the left, positive exponent. Move the decimal to the right, negative exponent.


What is 0.0000105 in scientific notation?

A number in scientific notation should have one number before the decimal place then two after. You move the decimal so this is true, then the number of places you moved the decimal will be the exponent. If you move the decimal to the right your exponent will be negative, if you move it to the left it will be positive. In this case you would move the decimal 5 places so you have 1.05x10^-5.


Express the number 0.000723 in specific notation?

7.23x10^-4. Move the decimal place to the right. The number of times you move the decimal is the same number as the exponent.


How do you change a number from scientific notation to decimal notation?

If the exponent is positive, you move the decimal point to the right, the specified number of digits. For a negative exponent, you move it to the left. In either case, you fill out missing digits with zero. Examples (using "^" for power):3.448 x 10^1 = 34.485 x 10^6 = 5000000 (note the implied decimal point to the right of the number)3 x 10^-3 = 0.003


What is the significance of the exponent to which 10 is raised when using scientific notation?

The exponent indicates how many spaces to move the decimal point to the right (+) or to the left (-) when expanded.


The in scientific notation tells you how many places to move the decimal?

The exponent of 10 tells you how many places to move the decimal point to the left if it is minus or to the right if it is plus.


When doing scientific notation is it negative if you move left?

No, if you shift the decimal point to the left, the exponent of base 10 is positive. The exponent of base 10 is negative if you shift the decimal point to the right.


HOW DO convert scientific notation to decimalnumbers?

The exponent tells you how many spaces to move the decimal, remember to add zeros as needed. If the exponent is negative make it a decimal number less than one by moving the decimal to the left. If the exponent is positive make the decimal number greater than one by moving the decimal to the right.


How do you convert 0.000067 to scientific notation?

Count how many places you move the decimal point until you get the number 6.7.If you move the decimal place to the left, the exponent is a positive number, but in this case you have to move the decimal point 5 places to the right so you will have a negative exponent.Answer: 6.7 x 10-5


How do you change scientific notation in positive exponent to standard form?

If the exponent is b, then you move the decimal point b places to the right - inserting zeros if necessary.


The exponent in scientific notation tells you how many places to move the?

decimal point exponent


What is 0.0000972 in scientific notation?

9.72 x 10-5 You put the decimal behind the first digit. Then count the number of places the decimal moved from its original position. This number becomes the exponent of the 10. If you move the decimal to the left, it is a positive number for the exponent. To the right, it is a negative exponent.


What is the scientific notation of 561?

5.61 x 102 , you just move the decimal so that the original number is greater than or equal to one but less than 10 then multiply that by 10 to the power of the number of decimal places you had to move. If you moved the decimal to the left, the exponent is positive, if you moved the decimal to the right, the exponent is negative.


How can you do scientific notation?

Some steps to convert the term into scientific notation:Determine the leading nonzero digit of the value.From the starting point, which is usually between two values, move the certain decimal places left/right until the decimal place takes place after the leading nonzero digit.Take note of how many decimal places you move the decimal point.For example, 1234.5061Move 3 decimal places to the left to get 1.2345061 x 10³.If you move the decimal point to the left, we obtain positive exponent for base 10.If you move the decimal point to the right ,we obtain negative exponent for base 10.Otherwise, if you don't move the decimal point at all, then we obtain zero exponent for base 10!


How do you convert a number from scientific notation to standard form?

You move the decimal point to the right, as many digits as the exponent states, filling out with zeroes if necessary. If the exponent is negative, you move the decimal point to the left. Example: 1 light-year has about 9.5 x 1012 kilometers. Moving the decimal point 12 digits to the right, you get: 9,500,000,000,000 kilometers.


What is 386 000 km in scientific notation?

3.86 x 105 Scientific notation is useful to get rid of seeing the zeros in a number. Count how many places you need to move your decimal place to have the last non zero number in the ones place and the rest of the numbers to the right of the decimal. The number of movements will be the exponent. When you are moving the decimal place to the left your exponent will be positive, when moving the decimal right, your exponent will be negative.


What way do you move a decimal to make a exponent a negative?

To the left, to the left everything moves to the left.


What is the scientific notation for 0.0000000007?

Move 10 decimal places to the right to get: 7 x 10-10 The exponent is negative since the leading nonzero digit takes place 10 decimal places on the right of the decimal places


How will you know the exponent of scientific notation is negative or positive?

The smaller number at the top right of the ten may or may not have a negative sign in front of it: like 6.2 x 102 or 6.2 x 10-2. If the little number is positive, the decimal in the first number will move to the right. If the exponent is negative, the decimal in the first number will move to the left.


When you multiply any number by ten what happens to the decimal point?

Move the decimal point to the right one time.


How do you convert scientific notation to decimal notation?

If the number in sci. notation has a positive exponent, move the decimal to the right the same number of spaces as the exponent's number. For example: 5.78 x 103 = 5780 If the exponent is negative, move the decimal to the left the same number of spaces as the exponent's number. For example: 2.945 x 10-5 = 0.00002945


How do you write scientific notation as a decimal?

You just treat scientific notation as a math problem. For example, 1.17*10^5 would be 1,17,000 (or in layman's terms, move the decimal point the number of spaces indicated by the exponent). If there's a negative exponent, that means you move the decimal to the left instead of to the right. For example, 1.17*10^-5 would be 0.0000117.


How do you write 8.2 in expanded form?

If you're talking about scientific notation you would take a number, for example, 0.00000056 and move the decimal to the rightso you have a number before and after the decimal (this case 5.7) and count how many place you move the decimal in this case 7. So to write it in scientific notation it would be 5.7 X 10 and 10 would have a ngative exponent, negative because the numbe is a decimal and we moved the decimal to the right. The exponent would be the number of places you move the decimal, 7. The scientific notation of 0.00000056= 5.6 X 10 to the negative seventh (-7 exponent) power. But to put it in it's expanded or original form you would have an equation like 5.6 X 10 to the -7th power. You would write out 5.6, and because you are multiplying by 10 you just have to move the decimal the number of places the exponent is and because the exponent is negative to the left for positive exponents to the right. So you have 5.6 and it's multiplyed by 10 with a negative exponent of 7 you would take the decimal and move it to the left 7 times so you get 0.00000056. The scientific method is just a simpler way of writing out long numbers with a lot of zeros. NOTE: If you have a positive exponent you move the decimial to the left to get scientific notation and right for expanded or original form.
