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.

When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
How do you make a negative exponent positive?
You can do it if you replace the base by its reciprocal.
What is x to the power minus 0.5?
A negative exponent means the same as a positive exponent in the denominator. Thus, x-0.5 = 1/x0.5. This, in turn, is equivalent to 1/(square root of x).
What do you do when multiplying a positive exponent by a negative exponent?
Example: (4x)-2 The answer to this would be 1/ 16x2. Multiply it out as if the negative exponent was not there ((4x)2), then that will be the denominator of the fraction. The numerator is one.
If the coefficient of the expression axn is negative and the exponent is positive will the expression be a polynomial?
true
How do you solve a positive number with a negative exponent?
turn the positive number into its recipricol and the put the number of the negative number on the top
How do you raise anumber to a negative exponent?
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
What does it mean when an exponent is a negative number?
A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100
What is the Definition of negative exponents?
A negative exponent simply means that the base is on the wrong side of the fraction line.For example, if you have x-2, you can turn this into a positive exponent by moving the base to the denominator and changing the sign on the exponent. The result would be:1--x2
When squaring a negative number if the factor is a negative and the exponent is positive will your answer be negative or positive?
If you square any real number it will always be positive.
What happens to a negative number with a positive exponent?
It will become a positive number.
How can an expression with a negative exponent be changed into one with a positive exponent?
Say it with a lot of sarcasm.
Why do you move a negative exponent to the other side of the fraction?
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.
Does the variable a with the exponent negative n equal 1 over a with the exponent of a positive n?
Yes.
What do you have to do to evaluate a negative exponent?
Find the reciprocal of the positive exponent. Thus, x-a = 1/xa
When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
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.
