Solution steps

128 = 82

Apply radical rule:

Apply radical rule:

a = a^{\frac{1}{2}}

2 = 2^{\frac{1}{2}}

Apply radical rule:

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

Apply exponent rule:

(a^{b})^{c} = a^{b c}, a \geq 0

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

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

\frac{1}{2} \cdot \frac{1}{3} = \frac{1}{6}

= 2 \cdot 2^{\frac{1}{6}}

Apply exponent rule:
