解答

展开

x^{'} \cdot (x + 1) + x (x + 1)^{^{'}}

xx' + x' + x (x + 1)^{'}

求解步骤

x^{'} (x + 1) + x (x + 1)^{^{'}}

乘开

x^{'} (x + 1) : x x^{'} + x^{'}

= x x^{'} + x^{'} + x (x + 1)^{^{'}}

e x p an d \frac{120 e ^{- 0.5 s}}{s ( s + 2 ) ( s + 5 )}

e x p an d - \frac{18}{( 2 + x ) ^{4}}

e x p an d \frac{6 x + 1}{( x + 1 ) ^{3} ( x ^{2} + 7 ) ^{2}}

e x p an d (15 - t^{2}) e^{t}

e x p an d \frac{5 ( x ^{2} ( 2 x ^{2} + 3 ) - 36 )}{12 x ^{4}}
