Question

Explain how you would fully simplify the expression below by naming the exponent law you would use, and state the operation you would perform on the exponents to simplify the expression. You must list the steps in the order they should be performed.

My teacher wants an explanation.

The expression is: (n^9n^-3)^-8/n^7

Answer 1

x^a * x^b = x^(a+b)
(x^a)^b = x^(ab)

now you can use those to calculate the correct power of n

Answer 2

(n^6)^-8/n^7
(n^(6 * -8) / n^7
n^-48 * n^-7
n^(-48-7)
n^-55
