simplify (\sqrt[8]{[9]})^4

Solution

simplify

Solution

3

Solution steps

Apply rule:

(a) = a

(9) = 9

Factor the number:

9 = 3^{2}

Apply radical rule:

= ((3^{2})^{\frac{1}{8}})^{4}

Apply exponent rule:

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

= (3^{2})^{\frac{1}{8} \cdot 4}

\frac{1}{8} \cdot 4 = \frac{1}{2}

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

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

= 3^{2}

Apply radical rule:

assuming

a \geq 0

= 3
