Question

I need help simplifying a math problem. It is (x^2 * x^-3)^4
The answer needs to have only positive exponents.
Also, can you explain how you got the answer pls.

Answer 1

$(x^2 \times x^{-3})^4 \\ \\ (x^{2-3})^4 \ / \ product \ rule \\ \\ (x^{-1})^4 \ / \ simplify \\ \\ x^{-4} \ / \ simplify \\ \\ \frac{1}{x^4} \ / \ negative \ power \ rule \\ \\ Answer: \frac{1}{x^4}$
