\frac{1}{X ^{6} + 24 X ^{4} + 192 X ^{2} + 512}

求解步骤

\frac{1}{( X ^{2} + 8 ) ^{3}}

(X^{2} + 8)^{3} = X^{6} + 24 X^{4} + 192 X^{2} + 512

= \frac{1}{X ^{6} + 24 X ^{4} + 192 X ^{2} + 512}

e x p an d (1 + tan (θ)) tan (2 θ)

e x p an d a (x + \frac{b}{2 a})^{2} - \frac{b ^{2}}{4 a} + c

\frac{d ^{3}}{d x ^{3}} ((y) (x^{4} - 2 x^{3} + 3 x - 1))

e x p an d (2 - \frac{1}{4 x})^{5}

e x p an d 1 + \frac{k}{m s ^{2}} (\frac{s + a}{s + b})
