求解步骤

π (e^{4} - 1)

使用分配律:

a (b - c) = ab - a c

a = π, b = e^{4}, c = 1

= π e^{4} - π 1

= e^{4} π - 1 π

乘以:

1 π = π

= e^{4} π - π

e x p an d - \frac{4}{3} cos (2) (x - \frac{π}{2})

\frac{d}{d x} ((z) (x^{2} + y^{2} - z^{2}))

e x p an d \frac{x}{( x - a ) ( x - b )}

s im pl i f y (x - 3) \times (x + 3)

e x p an d (m^{2} - 2 mn - 8 n^{2}) (m^{3} - 3 m^{2} n + 2, m n^{2})
