\frac{3}{( t + 1 ) ^{5}}

\frac{3}{t ^{5} + 5 t ^{4} + 10 t ^{3} + 10 t ^{2} + 5 t + 1}

求解步骤

\frac{3}{( t + 1 ) ^{5}}

(t + 1)^{5} = t^{5} + 5 t^{4} + 10 t^{3} + 10 t^{2} + 5 t + 1

= \frac{3}{t ^{5} + 5 t ^{4} + 10 t ^{3} + 10 t ^{2} + 5 t + 1}

e x p an d - \frac{1}{4} e^{- 8 t} + \frac{3}{49} (- 7 e^{- 7 t} t - e^{- 7 t})

e x p an d 3.924 x + 1.596 (e^{- 2.5 x} - 1)

e x p an d - x^{2} (1 + 2 ln (x))

e x p an d \frac{f x + n}{( x - d ) ^{2}}

e x p an d \frac{1}{2} x y^{2} (\frac{8 - x - 2 y}{4})^{2}
