Evaluate each expression for p=-4, q=8, and r=-10. 5r / 2p-3r

Insert either <, >, or = in the shaded area to make a true statement. $\(\frac{30}{40}\) - \(\frac{3}{4}\) \ \(\square\) \ \(\frac{14}{15}\) \(\cdot\) \(\frac{15}{14}\)$

Simplify each exponential expression. Assume that variables represent nonzero real numbers. $\(\frac{(x^{-2}\) y)^{-3}}{(x^{2} y^{-1})^{3}}$

Evaluate each expression for $p=-4$, $q=8$, and $r=-10$. $\frac{\frac{q}{2}-\frac{r}{3}}{\frac{3p}{4}+\frac{q}{8}}$

Simplify by reducing the index of the radical. $\sqrt[9]{x^6{y}^3}$
