化简 3/4 (-8)^{4/3}

解答

化简

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

12

求解步骤

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

(- 8)^{\frac{4}{3}} = 16

= 16 \cdot \frac{3}{4}

分式相乘:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{3 \cdot 16}{4}

数字相乘:

3 \cdot 16 = 48

= \frac{48}{4}

数字相除:

\frac{48}{4} = 12

= 12

49 x^{2} - 121

\frac{12}{5} + \frac{3}{4} + \frac{2}{3}

\frac{5 ^{9}}{5 ^{6}}

e^{x} > 3

\frac{- 3}{( - 3 ) ^{2}}
