2 (π x^{4} - π x)

2 π x^{4} - 2 π x

求解步骤

2 (π x^{4} - π x)

使用分配律:

a (b - c) = ab - a c

a = 2, b = π x^{4}, c = π x

= 2 π x^{4} - 2 π x

e x p an d (- d + 2 (\frac{84}{d}) - 2 = 0) d

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

e x p an d lo g_{(x + 1) (x + 2)} (x)

e x p an d \frac{5}{s ( s + 2 ) ( 0.5 s + 1 )}

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