expand (pi(5sqrt(5)-1))/6

expand

\frac{π ( 5 5 - 1 )}{6}

\frac{5 5 π}{6} - \frac{π}{6}

Solution steps

\frac{π ( 5 5 - 1 )}{6}

Expand

π (55 - 1) : 55 π - π

= \frac{5 5 π - π}{6}

Apply the fraction rule:

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

\frac{5 5 π - π}{6} = \frac{5 5 π}{6} - \frac{π}{6}

= \frac{5 5 π}{6} - \frac{π}{6}

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

\frac{d}{d t} ((h (t)) (4 t + 10))

- 3 + 5 i - (1 + 6 i, 4 - 2 i)

\frac{d}{d x} ((t - sin (t)) i) - (1 - cos (t)) j

\frac{( - 4 s ^{2} + 31 s - 54 )}{( s - 4 ) ^{3}}
