Question

I need help with number 13 and can you please write your answer using only positive exponents

Answer 1

`(1)/(x^(45))`

Step-by-step explanation:

The given expression is

`(x^(-5))^9`

In this case, we can multiply the exponents to get

`x^(-5\cdot9)=x^(-45)`

Then, to use positive exponents, we need to write it as a fraction

`(1)/(x^(45))`

Therefore, the answer is

`(1)/(x^(45))`
