expand-(3(-n-27pi^3))/(n^2)

expand

- \frac{3 ( - n - 27 π ^{3} )}{n ^{2}}

\frac{3}{n} + \frac{81 π ^{3}}{n ^{2}}

Solution steps

- \frac{3 ( - n - 27 π ^{3} )}{n ^{2}}

Expand

3 (- n - 27 π^{3}) : - 3 n - 81 π^{3}

= - \frac{- 3 n - 81 π ^{3}}{n ^{2}}

Apply the fraction rule:

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

\frac{- 3 n - 81 π ^{3}}{n ^{2}} = - (- \frac{3 n}{n ^{2}}) - (- \frac{81 π ^{3}}{n ^{2}})

= - (- \frac{3 n}{n ^{2}}) - (- \frac{81 π ^{3}}{n ^{2}})

Apply rule

- (- a) = a

= \frac{3 n}{n ^{2}} + \frac{81 π ^{3}}{n ^{2}}

Cancel

\frac{3 n}{n ^{2}} : \frac{3}{n}

= \frac{3}{n} + \frac{81 π ^{3}}{n ^{2}}

\frac{3 ( x ^{2} + 2 x + 6 )}{2}

4 x (x + 10 - 2 (x - 5) = 2^{2} - 4)

(u x^{3} - ln (x)) (x d u + u d x)

\frac{( x + 1 ) ( x + 4 )}{( x - 3 ) ( x + 5 ) ( x - 7 )}

([(1 + 0.22) - 1]^{1})^{2}
