化简 ((x^3)/(y^2))^{-1}

解答

化简

(\frac{x ^{3}}{y ^{2}})^{- 1}

\frac{y ^{2}}{x ^{3}}

求解步骤

(\frac{x ^{3}}{y ^{2}})^{- 1}

使用指数法则:

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

(\frac{x ^{3}}{y ^{2}})^{- 1} = \frac{1}{\frac{x ^{3}}{y ^{2}}}

= \frac{1}{\frac{x ^{3}}{y ^{2}}}

使用分式法则:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

= \frac{y ^{2}}{x ^{3}}

s im pl i f y (x^{2})^{- 1}

78. 2^{2} + 41. 3^{2} = c^{2}

s im pl i f y \frac{x y}{30} - \frac{x y}{12}

(x - 1)^{2} - 4 (x - 1) - 32 = 0

x^{2} - 3 x - 28 = 0
