Solution steps

\frac{1}{8 ^{\frac{2}{3}}}

Factor the number:

8 = 2^{3}

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

Apply exponent rule:

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

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

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

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

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

2^{2} = 4

= \frac{1}{4}
