expand (2(n+1+n3^n+3^n))/(n+3^{n+1)}

expand

\frac{2 \cdot ( n + 1 + n \cdot 3 ^{n} + 3 ^{n} )}{n + 3 ^{n + 1}}

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

Solution steps

\frac{2 ( n + 1 + n \cdot 3 ^{n} + 3 ^{n} )}{n + 3 ^{n + 1}}

Expand

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

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

(x^{2} - 5) e^{x}

\frac{( 2 x + 7 ) ^{2}}{4}

0.03 \cdot x (1. 2^{x})

(6 x + 7) (2 x - 14)
