simplify (\sqrt[3]{7x})^2

Solution

simplify

Solution

7^{\frac{2}{3}} x^{\frac{2}{3}}

Solution steps

Apply radical rule:

= ((7 x)^{\frac{1}{3}})^{2}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= (7 x)^{\frac{1}{3} \cdot 2}

\frac{1}{3} \cdot 2 = \frac{2}{3}

= (7 x)^{\frac{2}{3}}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

= 7^{\frac{2}{3}} x^{\frac{2}{3}}
