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 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


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.


What is 7.1 x 10 to the 4 power in standard form?

71000 Move the decimal to the right four spaces (the same number as the exponent).


What number is represented by 2.3 x 10-3?

The answer is 0.0023The interpretation is determined by the exponent of the 10.If the exponent is negative, then you move the decimal that # of places to the left.If the exponent is positive, then you move the decimal that # of places to the right.In your example, I moved the decimal three places to the right, and that gives me 0.0023.In the example, "7.53 x 10^4", I would move the decimal place four places to the right. Therefore, the number represented is 75,300Think of it simply like this if you don't get it. What is 5 x 10^1? You can better write this as 5 x 10 because 10 to the 1 power is just 10. It is easy, right? 5 x 10 = 50Well, 5 x 10^1 just means that you moved the decimal place over one place to the right. Isn't that what we did? 5.0 with the decimal place moved over to the right one place is 50.

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 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.)


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?

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.


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.


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.


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 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.
