8 (e^{- 0.4 t} - e^{- 0.6 t})

8 e^{- 0.4 t} - 8 e^{- 0.6 t}

求解步骤

8 (e^{- 0.4 t} - e^{- 0.6 t})

使用分配律:

a (b - c) = ab - a c

a = 8, b = e^{- 0.4 t}, c = e^{- 0.6 t}

= 8 e^{- 0.4 t} - 8 e^{- 0.6 t}

e x p an d (3 x + 8 y - 24 = 0,) (9 x - 2 y - 18 = 0)

e x p an d (7) (2 x - y = 13)

e x p an d (e^{x} sin (y) - 3 x^{2}) d x

e x p an d (r sin (θ) - 3)^{2}

e x p an d 5 (2^{x} + x)^{4} (2^{x} ln (2) + 1)
