化简 (5^1)/(5^4)

解答

化简

\frac{5 ^{1}}{5 ^{4}}

\frac{1}{125}

十进制

0.008

求解步骤

\frac{5 ^{1}}{5 ^{4}}

使用指数法则:

\frac{x ^{a}}{x ^{b}} = \frac{1}{x ^{b - a}}

= \frac{1}{5 ^{4 - 1}}

数字相减:

4 - 1 = 3

= \frac{1}{5 ^{3}}

5^{3} = 125

= \frac{1}{125}

\frac{1}{2 - x ^{2}} \geq \frac{16 x}{x ^{2} - 2} + 8 x

x^{2} + 10 x + 42 = - 3 x + 2

s im pl i f y \frac{- 5 - 2 i}{- 3 + 5 i}

1 = 7 x

s im pl i f y \frac{π}{2} - \frac{4 π}{11}
