Simplify each expression. Write all answers without using negative exponents. Assume that all variables are restricted to those numbers for which the expression is defined. $$\left(\frac{a^{2}}{b}\right)^{3}$$
Added by Michael C.
Step 1
First, we can simplify the expression inside the parentheses by multiplying the numerator and denominator by $b$: $$\frac{a^{2}}{b} \cdot \frac{b^{2}}{1} = \frac{a^{2}b^{2}}{b} = a^{2}b$$ Now we can raise this expression to the third power: $$(a^{2}b)^{3} = Show more…
