This is a procedure used to help people who are new to negative exponents. A negative exponent, when moved to the other side of the fraction, becomes a positive exponent and beginners are more comfortable with working with positive fractions.

What is 3m to the negative forth power?

It is the same as 1/34 . We move an exponent to the denominator and we change the exponent from positive to negative. Now 34 is 81 so the answer is 1/81 meters.If the exponent in the denominator is negative, we can move it up to the numerator and change it to a positive.


If you move the decimal to the right what happens to the exponent?

it becomes negative


What is .5 to the negative 1 exponent?

2. When a number is raised to a negative power, move it to the other side of the fraction. So, (0.5)^(-1) is the same as (1)/(0.5)^(1) or 1/(1/2). from there, just divide the fractions, and you will be left with 2.


What is x to the negative 7th power?

When we have x to a negative exponent we can move the x to the denominator and make the exponent positive. So x-7 is the same as 1/x7


What is a negative exponent?

When you have a number raised to a negative exponent, you move to the left rather than the right in decimal places. E.g. 103 = 1000 10-3 = 0.001 More specifically, when you have a negative exponent, you are taking the reciprocal of what the positive exponent would give. 24 = 16, but 2-4=(1/16) ■


What is x to negative 7th power?

When we have x to a negative exponent we can move the x to the denominator and make the exponent positive.So x-7 is the same as 1/x7 .In general if we have a-n then this is the same as 1/an .If you start with the negative in the denominator, then you can move it up to the numerator by changing the sign.


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 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 does it mean if the number written in scientific notation has a negative exponent?

It means that the decimal point has to move to the left.


What are negative exponents?

Exactly that ... negative exponents. For example: 1000 = 103 That is a positive exponent. .001 = 10-3 That is a negative exponent. For positive exponents, you move the decimal place that many positions to the right, adding zeros as needed. For negative exponents, you move the decimal place that many positions to the LEFT, adding zeros as needed. And, the special case is this: 100 = 1.


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 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.

How do you turn a negative exponent into a positive exponent?

Move the base number to the 'other side" of a division bar and change the exponent to the opposite sign. Example: 1/9 = 3^-2 becomes 1/(3^2) or 4 = 1/ (2^-2) becomes 2^2. Try it on your calculator to check your work.


In standard form what is 3.451x10-3?

Exponent is negative so move the point that number of places LEFT: 0.003451


What is the difference of exponent and scientific notation?

scientific notation tells how many times you will move or add zero either left(positive) or right (negative). exponent tells you how many times you will multiply its coefficient.


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

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


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 does a negative exponent mean in scientific notation?

For example, ten to the power -5 is the same as 1 divided by (10 to the power 5).In scientific notation, to expand the number, the negative exponent means that you must move the decimal point the specified number of positions to the LEFT. In the case of a positive exponent, you move the decimal point to the RIGHT, to expand the number.


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


Whicle converting a number to scientific notation if you move the decimal point four places to the left then the exponent that you use for the 10 will have a negative sign?

No, it will not.


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.


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.


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

decimal point exponent


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.
