E) X

F) X⁻⁷

G) X⁷√X

H) ⁹√a⁵

I) ⁵√a²

J) a³√a

K) 5b⁴

Explicação passo-a-passo:

A) √x * √x = (√x)² = x

B) 3 * √x + √x = 3√x + √x = 4√x

C) √a - 7 * √a = -6√a

D) $\frac{\sqrt[3]{x} }{\sqrt{x} } = \frac{\sqrt{x} * \sqrt{x} * \sqrt{x}}{\sqrt{x} } = \sqrt{x} * \sqrt{x} = (\sqrt{x})^{2} = x$

E) $\frac{x^{3}}{x^{2} } = \frac{x * x * x}{x * x} = x$

F) $x^{-3} * x^{-4} = x^{-7}$

G) $\sqrt{x} * x^{7} =x^{7}\sqrt{x}$

H) $\sqrt[3]{a} * \sqrt[3]{a^{4} } = \sqrt[9]{a^{5} }$

I) $\sqrt[4]{a} * \sqrt[]{a} = \sqrt[5]{a^{2} }$

J) $(\sqrt{a})^{3} * a^{2} = \sqrt{a} * a * a^{2} = \sqrt{a} * a^{3} = a^{3}\sqrt{a}$

K) $\sqrt{5}^{2} * b^{4} = \sqrt{25} * b^{4} = 5 *b^{4} = 5b^{4}$
