expand (20e^4)/((1+e^4)^2)

expand

\frac{20 e ^{4}}{( 1 + e ^{4} ) ^{2}}

\frac{20 e ^{4}}{1 + 2 e ^{4} + e ^{8}}

Solution steps

\frac{20 e ^{4}}{( 1 + e ^{4} ) ^{2}}

(1 + e^{4})^{2} = 1 + 2 e^{4} + e^{8}

= \frac{20 e ^{4}}{1 + 2 e ^{4} + e ^{8}}

\frac{1}{x ^{n} ( x - a )}

(e^{- t} - e^{(- 2 t)})^{2}

f (x^{5} - 3 x^{3} + 9) d x

(e^{- 2 x} + 4) d y

(e^{2 y} + e^{- 2 y})^{2}
