化简 (2n^{1/3}(3n^{1/3}-4n^{4/3}))/(2n^{-1/3)}

解答

化简

\frac{2 n ^{\frac{1}{3}} ( 3 n ^{\frac{1}{3}} - 4 n ^{\frac{4}{3}} )}{2 n ^{- \frac{1}{3}}}

n^{\frac{2}{3}} (3 n^{\frac{1}{3}} - 4 n^{\frac{4}{3}})

求解步骤

\frac{2 n ^{\frac{1}{3}} ( 3 n ^{\frac{1}{3}} - 4 n ^{\frac{4}{3}} )}{2 n ^{- \frac{1}{3}}}

约分:

2

= \frac{n ^{\frac{1}{3}} ( 3 n ^{\frac{1}{3}} - 4 n ^{\frac{4}{3}} )}{n ^{- \frac{1}{3}}}

化简

\frac{n ^{\frac{1}{3}}}{n ^{- \frac{1}{3}}} : n^{\frac{2}{3}}

= n^{\frac{2}{3}} (3 n^{\frac{1}{3}} - 4 n^{\frac{4}{3}})
