Solution

simplify

(- \frac{64}{27})^{\frac{1}{3}}

Solution

- \frac{4}{3}

+1

Decimal Notation

- 1.33333 \dots

Solution steps

(- \frac{64}{27})^{\frac{1}{3}}

Apply exponent rule:

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

if

n

is odd

(- \frac{64}{27})^{\frac{1}{3}} = - (\frac{64}{27})^{\frac{1}{3}}

= - (\frac{64}{27})^{\frac{1}{3}}

Apply exponent rule:

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

(\frac{64}{27})^{\frac{1}{3}} = \frac{6 4 ^{\frac{1}{3}}}{2 7 ^{\frac{1}{3}}}

= - \frac{6 4 ^{\frac{1}{3}}}{2 7 ^{\frac{1}{3}}}

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

= - \frac{4}{2 7 ^{\frac{1}{3}}}

2 7^{\frac{1}{3}} = 3

= - \frac{4}{3}
