\frac{16}{( s ^{2} + 4 ) ^{2}}

\frac{16}{s ^{4} + 8 s ^{2} + 16}

求解步骤

\frac{16}{( s ^{2} + 4 ) ^{2}}

(s^{2} + 4)^{2} = s^{4} + 8 s^{2} + 16

= \frac{16}{s ^{4} + 8 s ^{2} + 16}

e x p an d (x^{2} + 2 x + 3)^{7}

e x p an d (a + b x + cy + d x^{2} + e y^{2} + f x y)^{2}

e x p an d 10 c + 10 - (\frac{100 ( 2 c - 8 )}{c ^{2} - 8 c + 20})

e x p an d e^{(y - \frac{( z - y ) ^{2}}{2 l ^{2} - t})}

e x p an d \frac{1}{( z - 2 ) ( z - 1 )}
