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

Solution

simplify

3 (2 x)^{2}

Solution

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

Solution steps

3 (2 x)^{2}

Apply radical rule:

n a = a^{\frac{1}{n}}

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

Apply exponent rule:

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

assuming

a \geq 0

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

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

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

Apply exponent rule:

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

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