\frac{( - 4 t ^{4} + 32 t )}{( 4 + t ^{3} ) ^{2}}

\frac{- 4 t ^{4} + 32 t}{16 + 8 t ^{3} + t ^{6}}

求解步骤

\frac{- 4 t ^{4} + 32 t}{( 4 + t ^{3} ) ^{2}}

(4 + t^{3})^{2} = 16 + 8 t^{3} + t^{6}

= \frac{- 4 t ^{4} + 32 t}{16 + 8 t ^{3} + t ^{6}}

e x p an d 4 y^{2} d x - (3 - y ln (y)) d y

e x p an d 10 \cdot (2.54 - (\frac{2.537}{x}) = 25.43)

e x p an d 9800 (220 π - \frac{250}{3})

e x p an d \frac{3 ( 5 m - 7 )}{4 m + 8}

e x p an d - \frac{2}{13 ( s ^{2} + 4 )}
