化简 (5ab^3)/(25a^2b^2)

解答

化简

\frac{5 a b ^{3}}{25 a ^{2} b ^{2}}

\frac{b}{5 a}

求解步骤

\frac{5 a b ^{3}}{25 a ^{2} b ^{2}}

因式分解数字:

25 = 5 \cdot 5

= \frac{5 a b ^{3}}{5 \cdot 5 a ^{2} b ^{2}}

约分:

5

= \frac{a b ^{3}}{5 a ^{2} b ^{2}}

化简

\frac{b ^{3}}{b ^{2}} : b

= \frac{ab}{5 a ^{2}}

化简

\frac{a}{a ^{2}} : \frac{1}{a}

= \frac{b}{5 a}

x^{2} + 2 x = 0
