化简 (4/6)^3

解答

化简

(\frac{4}{6})^{3}

\frac{8}{27}

十进制

0.29629 \dots

求解步骤

(\frac{4}{6})^{3}

使用指数法则:

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

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

4^{3} = 64

= \frac{64}{6 ^{3}}

6^{3} = 216

= \frac{64}{216}

约分:

8

= \frac{8}{27}

s im pl i f y 28 + 463 - 27

f a c t or 2 x^{3} - x^{2} - 50 x + 25

y^{2} + 16 y = 17

x^{2} + \frac{5}{2} x + 1 = 0

s im pl i f y \frac{4}{b - 8} + \frac{7}{b ^{2} - 64}
