expand (s^4+81)/(s(s^2+9)^2)

expand

\frac{s ^{4} + 81}{s ( s ^{2} + 9 ) ^{2}}

\frac{s ^{4} + 81}{s ^{5} + 18 s ^{3} + 81 s}

Solution steps

\frac{s ^{4} + 81}{s ( s ^{2} + 9 ) ^{2}}

(s^{2} + 9)^{2} = s^{4} + 18 s^{2} + 81

= \frac{s ^{4} + 81}{s ( s ^{4} + 18 s ^{2} + 81 )}

Expand

s (s^{4} + 18 s^{2} + 81) : s^{5} + 18 s^{3} + 81 s

= \frac{s ^{4} + 81}{s ^{5} + 18 s ^{3} + 81 s}

(y + x) d x

(10 sin (x) - 1) (10 sin (x) + 1)

\frac{( 5 - x ) ^{2}}{2}

n (\frac{ln ( n + 1 )}{ln ( n )} - 1)

\frac{( 2 x + 5 ) ^{2}}{4}
