Simplify the radical.

$\sqrt{75}$

Simplify the radical.

$\sqrt{180}$

Simplify the radical.

$\sqrt{63x^2}$

True or False:

$\sqrt{9+16}$ and $\sqrt9+\sqrt{16}$ are equal.

Evaluate each expression in Exercises 1–12, or indicate that the root is not a real number. √144+√25

Use the product rule to simplify the expressions in Exercises 13–22. In Exercises 17–22, assume that variables represent nonnegative real numbers. $\sqrt{2x^2}\cdot \sqrt{6x}$

Use the quotient rule to simplify the expressions in Exercises 23–32. Assume that x > 0. $\frac{\sqrt{150x^4}}{\sqrt{3x}}$
