Question
Simplify each expression. Assume that all variables represent positive real numbers. Write answers with only positive exponents.$$\left(\frac{a^{-1}}{b^{2}}\right)^{-3}$$
Step 1
So, we multiply the exponents inside the parentheses by -3. $$ \left(\frac{a^{-1}}{b^{2}}\right)^{-3} = \frac{a^{-1 \cdot -3}}{b^{2 \cdot -3}} = \frac{a^{3}}{b^{-6}} $$ Show more…
