expand ((x^4+1)^2)/(x^8+1)

expand

\frac{( x ^{4} + 1 ) ^{2}}{x ^{8} + 1}

\frac{x ^{8} + 2 x ^{4} + 1}{x ^{8} + 1}

Solution steps

\frac{( x ^{4} + 1 ) ^{2}}{x ^{8} + 1}

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

= \frac{x ^{8} + 2 x ^{4} + 1}{x ^{8} + 1}

(x^{3} - x + 30)^{6}

(3 + 2)^{5}

122 (e^{(- 0.18 t)} - e^{(- t)})

\frac{e ^{a}}{( 1 + e ^{a} ) ^{2}}

\frac{a s ^{2} + 2 s + 2}{s ( s ^{2} + 2 s + 2 )}
