Use

1) The definition of exponentaiton:

a^{b}=a\cdot a\cdot a \cdot ... \cdot a, b times)

2) The rule for multiplying fractions:

\frac{a}{b}\cdot\frac{c}{d}=\frac{ac}{bd}

To Prove

(\frac{a}{b})^{n}=\frac{a^n}{b^n}

Which of the following rules are true?

Decide if the statement of equality is true or false. Use the "show your work" box to prove or explain your answer.

(\frac{b}{a})^{-1}=\frac{a}{b}
