Answer

$$\frac{y}{3xy^{-1}}$$

Work Step by Step

We know the following rules of exponents. The list of names is on page 330. $$ (1) \ a^m\cdot a^n = a^{m+n} \\ (2) \ (ab)^m =a^mb^m \\ (3) \ (a^m)^n =a^{mn} \\ (4) \ a^{-m} = \frac{1}{a^m} \\ (5)\ \frac{a^m}{a^n} =a^{m-n} \\ (6) \ a^0=1 \\ (7) \ (\frac{a}{b})^m =\frac{a^m}{b^m}$$ Thus, we find: $$\frac{y}{3y^{-1}x^{3-2}} \\ \frac{y}{3xy^{-1}} \\ \frac{y}{3xy^{-1}}$$
