Question

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

Answer 1

Answer:

$\frac{1}{x^{45}}$

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

$\frac{1}{x^{45}}$

Therefore, the answer is

$\frac{1}{x^{45}}$
