expand (2^{n-1})/(n^2(n+1))

expand

\frac{2 ^{n - 1}}{n ^{2} ( n + 1 )}

\frac{2 ^{n - 1}}{n ^{3} + n ^{2}}

Solution steps

\frac{2 ^{n - 1}}{n ^{2} ( n + 1 )}

Expand

n^{2} (n + 1) : n^{3} + n^{2}

= \frac{2 ^{n - 1}}{n ^{3} + n ^{2}}

(e^{x} - 2)^{3}

\frac{d}{d y} ((z) (z^{3} - x y + y z + y^{3} - 2))

\frac{1 + sin ( x ) ( 1 - sin ( x ) )}{cos ( x )}

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

24 e^{(- 20 t)} + 20 (\frac{6}{5} - \frac{6}{5} e^{(- 20 t)})
