化简 (u^{1/3})^{4/5}

解答

化简

(u^{\frac{1}{3}})^{\frac{4}{5}}

u^{\frac{4}{15}}

求解步骤

(u^{\frac{1}{3}})^{\frac{4}{5}}

使用指数法则:

(a^{b})^{c} = a^{b c},

假定

a \geq 0

= u^{\frac{1}{3} \cdot \frac{4}{5}}

\frac{1}{3} \cdot \frac{4}{5} = \frac{4}{15}

= u^{\frac{4}{15}}

x - 3 > 5 or x + 3 < - 2

f a c t or (x - 2)^{2} + 8 (x - 2) + 15

s im pl i f y 7 a - 5 a

s im pl i f y \frac{3}{6} - \frac{1}{4}

y^{2} - y - 12 > 0
