化简 (12k^8)/(4(k^5)^2)

解答

化简

\frac{12 k ^{8}}{4 ( k ^{5} ) ^{2}}

\frac{3}{k ^{2}}

求解步骤

\frac{12 k ^{8}}{4 ( k ^{5} ) ^{2}}

化简

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

= \frac{12 k ^{8}}{4 k ^{10}}

因式分解数字:

12 = 4 \cdot 3

= \frac{4 \cdot 3 k ^{8}}{4 k ^{10}}

约分:

4

= \frac{3 k ^{8}}{k ^{10}}

化简

\frac{k ^{8}}{k ^{10}} : \frac{1}{k ^{2}}

= \frac{3}{k ^{2}}
