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

expand

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

\frac{n ^{4}}{2} + \frac{n ^{2}}{2}

Solution steps

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

Expand

n^{2} (n^{2} + 1) : n^{4} + n^{2}

= \frac{n ^{4} + n ^{2}}{2}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{n ^{4} + n ^{2}}{2} = \frac{n ^{4}}{2} + \frac{n ^{2}}{2}

= \frac{n ^{4}}{2} + \frac{n ^{2}}{2}

\frac{x ^{2} - 25 y}{5 ( 5 x + 25 y )}

f (x) = x + 6 - 3

2 \cdot 2.4 - 4 \cdot 0.8

(2 x + e^{x}) (x^{2} \cdot e^{x})

\frac{0.1 ( - 2 s + 5 )}{s}
