Simplify each expression. Assume that all variables represent positive values. Assume no division by 0. SEE EXAMPLE 6. (OBJECTIVE 3) $$\left(\frac{32}{243}\right)^{1 / 5}$$

Find each square root. If it is not exact, give a decimal approximation correct to three decimal places. $$\sqrt{\frac{576}{625}}$$

Simplify. Assume that all variables in the radicand of an even root represent positive values. Assume no division by 0. Express each answer with positive exponents only. $$(-8)^{1 / 3}$$

Simplify. All variables represent positive values. $$\sqrt{108}-\sqrt{75}$$

Simplify each expression. All variables of square root expressions represent positive numbers. Assume no division by 0. $$\sqrt{\frac{180 a^{3} b}{b^{3}}}$$

Simplify each radical expression. If the answer is not exact, round to the nearest hundredth. All variables represent positive values $$\sqrt[3]{27 y^{3} z^{6}}$$
