expand (e^{-m})/((1+e^{-m))^2}

expand

\frac{e ^{- m}}{( 1 + e ^{- m} ) ^{2}}

\frac{e ^{- m}}{1 + 2 e ^{- m} + e ^{- 2 m}}

Solution steps

\frac{e ^{- m}}{( 1 + e ^{- m} ) ^{2}}

(1 + e^{- m})^{2} = 1 + 2 e^{- m} + e^{- 2 m}

= \frac{e ^{- m}}{1 + 2 e ^{- m} + e ^{- 2 m}}

(1, - 1) y (1, 5)

e^{- 2 l n (\frac{1}{5})}

(3 x^{4} y^{7}) (5 x^{2} y)

2 x^{4} e^{- 2 x}
