simplify (-3^3)^{1/3}

Solution

simplify

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

Solution

- 3

Solution steps

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

Apply exponent rule:

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

if

n

is odd

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

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

Apply exponent rule:

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

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

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

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

= - 3^{1}

Apply exponent rule:

a^{1} = a

3^{1} = 3

= - 3
