simplify \sqrt[4]{(-3)^3}

Solution

simplify

Solution

(- 1)^{\frac{3}{4}} \cdot 3^{\frac{3}{4}}

Solution steps

Apply radical rule:

= ((- 3)^{3})^{\frac{1}{4}}

Apply exponent rule:

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

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

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

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

Apply exponent rule:

(- a)^{\frac{m}{n}} = (- 1)^{\frac{m}{n}} (a)^{\frac{m}{n}}

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

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