Solution

simplify

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

Solution

16

Solution steps

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

Apply exponent rule:

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

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

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

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

= 1 \cdot 8^{\frac{4}{3}}

8^{\frac{4}{3}} = 16

= 1 \cdot 16

Multiply the numbers:

1 \cdot 16 = 16

= 16
