How to do exponents?

Question

Use the power of a product rule for exponents to simplify the expression.

(-2r^3s^5)^5

I want to know HOW to do this?

Answer 1

(-2r³s⁵)⁵

Recall : The power of product rule (9a^mbⁿ)^r =(9^r)(a^mr)(b^nr)

                      =(-2)⁵ (r³)⁵(s⁵)⁵

Simplify the expression

                     = -32r¹⁵s²⁵.
