expand (8k^3s)/((s^2+k^2)^3)

expand

\frac{8 k ^{3} s}{( s ^{2} + k ^{2} ) ^{3}}

\frac{8 k ^{3} s}{s ^{6} + 3 k ^{2} s ^{4} + 3 k ^{4} s ^{2} + k ^{6}}

Solution steps

\frac{8 k ^{3} s}{( s ^{2} + k ^{2} ) ^{3}}

(s^{2} + k^{2})^{3} = s^{6} + 3 k^{2} s^{4} + 3 k^{4} s^{2} + k^{6}

= \frac{8 k ^{3} s}{s ^{6} + 3 k ^{2} s ^{4} + 3 k ^{4} s ^{2} + k ^{6}}

(\frac{m}{k} - k) (2 m - 1) n

2 ((x + 1) (x + 2) (x - 1) (x - 1)^{2})

\frac{t ( t - 20 )}{3 ( t - 4 ) ^{2}}

(x + 1) (x - \frac{7}{9})

\frac{( 1 - y ) ^{3}}{3}
