化简 (6ab^5)/(12a^4b^3)

解答

化简

\frac{6 a b ^{5}}{12 a ^{4} b ^{3}}

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

求解步骤

\frac{6 a b ^{5}}{12 a ^{4} b ^{3}}

因式分解数字:

12 = 6 \cdot 2

= \frac{6 a b ^{5}}{6 \cdot 2 a ^{4} b ^{3}}

约分:

6

= \frac{a b ^{5}}{2 a ^{4} b ^{3}}

化简

\frac{b ^{5}}{b ^{3}} : b^{2}

= \frac{a b ^{2}}{2 a ^{4}}

化简

\frac{a}{a ^{4}} : \frac{1}{a ^{3}}

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