展开 ln(1+a(e^x-1))

解答

展开

ln (1 + a (e^{x} - 1))

ln (1 + a e^{x} - a)

求解步骤

ln (1 + a (e^{x} - 1))

乘开

1 + a (e^{x} - 1) : 1 + a e^{x} - a

= ln (1 + a e^{x} - a)

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

e x p an d A (3, 4) y B (5, - 1)

e x p an d p (- 3, 10) p (6, - 4)

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

e x p an d (1, - 2) \cdot (x, y)
