0.00289867 (e^{- 2.40187 t} - e^{- 26.0214 t})

使用分配律:

a (b - c) = ab - a c

a = 0.00289867, b = e^{- 2.40187 t}, c = e^{- 26.0214 t}

= 0.00289867 e^{- 2.40187 t} - 0.00289867 e^{- 26.0214 t}

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

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

e x p an d (e^{x}) (\frac{1}{2} e^{- 3 x} + \frac{1}{2} e^{3 x})

e x p an d \frac{5 x ^{2} + 7 x + 4}{( x + 1 ) ( x ^{2} + 3 x + 3 )}

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