化简 (3(w^5)^2)/(12w^9)

解答

化简

\frac{3 ( w ^{5} ) ^{2}}{12 w ^{9}}

\frac{w}{4}

求解步骤

\frac{3 ( w ^{5} ) ^{2}}{12 w ^{9}}

化简

(w^{5})^{2} : w^{10}

= \frac{3 w ^{10}}{12 w ^{9}}

因式分解数字:

12 = 3 \cdot 4

= \frac{3 w ^{10}}{3 \cdot 4 w ^{9}}

约分:

3

= \frac{w ^{10}}{4 w ^{9}}

化简

\frac{w ^{10}}{w ^{9}} : w

= \frac{w}{4}
