5.2 Exercise 31

Simplify each expression by applying several properties:

ⓐ $\left(3 x^{2} y\right)^{4} \left(2 x y^{2}\right)^{3}$ ⓑ $\frac{\left(x^{3}\right)^{4} \left(x^{−2}\right)^{5}}{\left(x^{6}\right)^{5}}$ ⓒ $\left(\frac{2 x y^{2}}{x^{3} y^{−2}}\right)^{2} \left(\frac{12 x y^{3}}{x^{3} y^{−1}}\right)^{−1} .$
