simplify (-27/8)^{4/3}

Solution

simplify

(- \frac{27}{8})^{\frac{4}{3}}

Solution

\frac{81}{16}

+1

Decimal Notation

5.0625

Solution steps

(- \frac{27}{8})^{\frac{4}{3}}

Apply exponent rule:

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

(- \frac{27}{8})^{\frac{4}{3}} = (- 1)^{\frac{4}{3}} (\frac{27}{8})^{\frac{4}{3}}

= (- 1)^{\frac{4}{3}} (\frac{27}{8})^{\frac{4}{3}}

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

= 1 \cdot (\frac{27}{8})^{\frac{4}{3}}

Apply exponent rule:

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

(\frac{27}{8})^{\frac{4}{3}} = \frac{2 7 ^{\frac{4}{3}}}{8 ^{\frac{4}{3}}}

= 1 \cdot \frac{2 7 ^{\frac{4}{3}}}{8 ^{\frac{4}{3}}}

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

= 1 \cdot \frac{2 7 ^{\frac{4}{3}}}{16}

2 7^{\frac{4}{3}} = 81

= 1 \cdot \frac{81}{16}

Multiply:

1 \cdot \frac{81}{16} = \frac{81}{16}

= \frac{81}{16}
