3 + 3 (x + \frac{π}{4})

3 + 3 x + \frac{3 π}{4}

求解步骤

3 + 3 (x + \frac{π}{4})

乘开

3 (x + \frac{π}{4}) : 3 x + \frac{3 π}{4}

= 3 + 3 x + \frac{3 π}{4}

e x p an d (r + d r)^{3}

e x p an d 2 3 + 5 + 13 + 48 = a + b

e x p an d (3 x + 2 e)^{3}

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