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

expand

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

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

Solution steps

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

Expand

n (n + 1) \cdot 2^{n + 1} : 2^{n + 1} n^{2} + 2^{n + 1} n

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

\frac{2 ( z - 8 )}{3}

(3 + 1)^{2}

2 (e^{9} - 1)

\frac{1}{s ^{2} ( s ^{2} - 4 s )}

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