化简 (-6p^2q)/(-2q^3)

解答

化简

\frac{- 6 p ^{2} q}{- 2 q ^{3}}

\frac{3 p ^{2}}{q ^{2}}

求解步骤

\frac{- 6 p ^{2} q}{- 2 q ^{3}}

使用分式法则:

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

= \frac{6 p ^{2} q}{2 q ^{3}}

因式分解数字:

6 = 2 \cdot 3

= \frac{2 \cdot 3 p ^{2} q}{2 q ^{3}}

约分:

2

= \frac{3 p ^{2} q}{q ^{3}}

化简

\frac{q}{q ^{3}} : \frac{1}{q ^{2}}

= \frac{3 p ^{2}}{q ^{2}}

17 = - 13 - 8 x

f a c t or 4 x^{2} + 2 x y - 10 x - 5 y

- 2 ∣ h - 7 ∣ = - 28

\frac{1}{x - 3} + \frac{1}{x + 2} \geq \frac{2 x}{x ^{2} + x - 2}

f a c t or x^{3} - x^{2} - 14 x + 24
