Simplify Each Expression $\sqrt[5]{243}$ (B) $\sqrt[3]{\frac{5}{9}}$ (C) $\sqrt{28 x^{6} y^{3}}$ (D) $\frac{\sqrt[5]{p q} \sqrt[5]{p q^{2}}}{\sqrt[5]{p^{4}}}$

Short Answer

Simplify each expression. Assume that all variables represent positive real numbers.
(a) $\sqrt[5]{243}$
(b) $\sqrt[3]{\frac{5}{9}}$
(c) $\sqrt{28 x^{6} y^{3}}$
(d) $\frac{\sqrt[5]{p q} \sqrt[5]{p q^{2}}}{\sqrt[5]{p^{4}}}$
