simplify \sqrt[4]{256^3}

Solution

simplify

Solution

64

Solution steps

Apply radical rule:

= (25 6^{3})^{\frac{1}{4}}

Apply exponent rule:

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

= 25 6^{3 \cdot \frac{1}{4}}

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

= 25 6^{\frac{3}{4}}

Factor the number:

256 = 4^{4}

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

Apply exponent rule:

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

(4^{4})^{\frac{3}{4}} = 4^{4 \cdot \frac{3}{4}} = 4^{3}

= 4^{3}

Refine

= 64
