expand 1/((1-3/4 e^{-x))(1-1/2 e^{-x})}

expand

\frac{1}{( 1 - \frac{3}{4} e ^{- x} ) ( 1 - \frac{1}{2} e ^{- x} )}

\frac{1}{1 - \frac{5}{4} e ^{- x} + \frac{3}{8} e ^{- 2 x}}

Solution steps

\frac{1}{( 1 - \frac{3}{4} e ^{- x} ) ( 1 - \frac{1}{2} e ^{- x} )}

Expand

(1 - \frac{3}{4} e^{- x}) (1 - \frac{1}{2} e^{- x}) : 1 - \frac{5}{4} e^{- x} + \frac{3}{8} e^{- 2 x}

= \frac{1}{1 - \frac{5}{4} e ^{- x} + \frac{3}{8} e ^{- 2 x}}
