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

e^{x} x + e^{x}

求解步骤

e^{x} (x + 1)

使用分配律:

a (b + c) = ab + a c

a = e^{x}, b = x, c = 1

= e^{x} x + e^{x} \cdot 1

= e^{x} x + 1 \cdot e^{x}

乘以:

1 \cdot e^{x} = e^{x}

= e^{x} x + e^{x}

e x p an d \frac{1}{4} c - 3 (\frac{1}{2} c + 3 = - \frac{3}{4} c)

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

e x p an d 0.03 \cdot 10 (1. 2^{10})

e x p an d \frac{( X ^{2} )}{( 1 - X ) ( 0.5 - X )}

e x p an d \frac{12 x + 36}{x ^{2} ( x + 6 ) ^{2}}
