求解步骤

2 (e^{4} - e)

使用分配律:

a (b - c) = ab - a c

a = 2, b = e^{4}, c = e

= 2 e^{4} - 2 e

e x p an d \frac{8 x ( x ^{2} - 4 )}{( 4 x ^{4} - 32 x ^{2} + 289 ) ^{\frac{1}{2}}}

e x p an d 3 (2 x - 8 = 6)

\frac{d}{d y} ((x) (1 + sin (\frac{π x}{4})))

e x p an d \frac{f ( x + h ) - f ( x ^{2} - 1 )}{h}

e x p an d \frac{( 2 x + 1 ) ^{4}}{x ^{2} + x + 2}
