化简

(\frac{1}{5})^{2}

\frac{1}{25}

十进制

0.04

求解步骤

(\frac{1}{5})^{2}

使用指数法则:

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

= \frac{1 ^{2}}{5 ^{2}}

1^{2} = 1

= \frac{1}{5 ^{2}}

5^{2} = 25

= \frac{1}{25}

- 4 ∣ 4 m - 2 ∣ + 4 = - 8

s im pl i f y \frac{3 ^{5}}{3 ^{8}}

(x - 3)^{2} + 9 = 25

- 4 + 3 x - 5 x = - 1 - 10 + x

s im pl i f y \frac{x - \frac{x}{y}}{y - \frac{y}{x}}
