simplify (\sqrt[4]{7x})^3

Solution

simplify

Solution

7^{\frac{3}{4}} x^{\frac{3}{4}}

Solution steps

Apply radical rule:

= ((7 x)^{\frac{1}{4}})^{3}

Apply exponent rule:

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

= (7 x)^{\frac{1}{4} \cdot 3}

\frac{1}{4} \cdot 3 = \frac{3}{4}

= (7 x)^{\frac{3}{4}}

Apply exponent rule:

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

= 7^{\frac{3}{4}} x^{\frac{3}{4}}
