Question

Simplify both questions and give full explanation please

Answer 1

First question: 1/x^-7

Second question:

x^7

Explanation:

To divide these problems (same variable base and exponents) subtract the exponents.

To get rid of a negative on the exponent, "push" the term across the fraction bar. Passing over the fraction bar changes the sign of the exponent. There are math reasons for this, its not random. But thats how it works. (Has to do with an exponent of -1 which will give you the reciprocal of your base).

Also, to multiply terms with the same base, add the exponents.
