Question

I have a quick question. to square a number that is written as a power of 10 who do you do to their exponents? can you give an example of how that would be written out. I believe you multiply. But I want to see thanks

Answer 1

\[
(x^n)^m = \underbrace{x^n\cdot x^n\cdot \ldots x^n}_{m}
\]

Answer 2

\[
=x ^{\overbrace{n+n+\ldots +n}^{m}} = x^{n\cdot m}
\]
