Question

Simplify each exponential expression using the appropriate rule of exponents

Answer 1

well this is the power of a power law

which means the outer most power ), operates on each part of the term in the brackets.

and the rule is multiply the powers

\[(ab^n)^m = a^m \times b^{n \times m}\]

\[x^0 = 1\]

hope it helps
