化简 (5x)^{-2}

解答

化简

(5 x)^{- 2}

\frac{1}{25 x ^{2}}

求解步骤

(5 x)^{- 2}

使用指数法则:

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

(5 x)^{- 2} = \frac{1}{( 5 x ) ^{2}}

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

化简

(5 x)^{2} : 25 x^{2}

= \frac{1}{25 x ^{2}}

\frac{3}{4} - \frac{1}{2} n = \frac{5}{8}

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

s im pl i f y (e^{x^{2}})^{2}

f a c t or x^{3} - 10 x^{2} + 28 x - 24

x^{2} + 4 x - 12 \leq 0
