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.
it becomes negative
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
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) ■
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.
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
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.
it becomes negative
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.
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

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.
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.
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.
It means that the decimal point has to move to the left.
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.
Exponent is negative so move the point that number of places LEFT: 0.003451
