Solution

simplify

+ (- \frac{8}{125})^{\frac{1}{3}}

Solution

- \frac{2}{5}

+1

Decimal Notation

Solution steps

(- \frac{8}{125})^{\frac{1}{3}}

Apply exponent rule:

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

if

n

is odd

(- \frac{8}{125})^{\frac{1}{3}} = - (\frac{8}{125})^{\frac{1}{3}}

= - (\frac{8}{125})^{\frac{1}{3}}

Apply exponent rule:

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

(\frac{8}{125})^{\frac{1}{3}} = \frac{8 ^{\frac{1}{3}}}{12 5 ^{\frac{1}{3}}}

= - \frac{8 ^{\frac{1}{3}}}{12 5 ^{\frac{1}{3}}}

8^{\frac{1}{3}} = 2

= - \frac{2}{12 5 ^{\frac{1}{3}}}

12 5^{\frac{1}{3}} = 5

= - \frac{2}{5}
