You can do it if you replace the base by its reciprocal.

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 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
What is positive exponents?
Exponents that are NOT a negative exponent therefore they are mostly whole numbers kind of:)
If the coefficient of the expression axn is a fraction and the exponent is positive will the expression be a polynomial?
Not necessarily. Every exponent in the exponent must be a non-negative integer. This is not what you have specified. For example, if n = 3.5, it is not a term in a polynomial expression.
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 a negative exponent mean?
"Dose" is a measured portion of a medicine. I am not aware of any exponents that have anything to do with measured quantities of medication! A negative exponent is simply the reciprocal of the corresponding positive exponent. Thus x^(-a) = (1/x)^a for non-zero x.
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 should you do to make a negative exponent positive in a reciprocal way?
An expression with a negative exponent is equivalent to the positive exponent of its reciprocal. Thus, 3-4 = 1/34 or, equivalently, (1/3)4 or (3/4)-2 = (4/3)2
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
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.
