## Thinking Mathematically (6th Edition)

Simplify the provided expression to obtain, $\frac{{{a}^{n}}}{{{b}^{0}}}=\frac{{{a}^{n}}}{1}$ Because ${{b}^{0}}=1$ and not zero. $\frac{{{a}^{n}}}{1}={{a}^{n}}$ As$\frac{{{a}^{n}}}{{{b}^{0}}}$ is not undefined because${{b}^{0}}=1$ and not zero, hence it does not make sense.
