\frac{d x}{( x - 3 ) ^{5}}

\frac{d x}{x ^{5} - 15 x ^{4} + 90 x ^{3} - 270 x ^{2} + 405 x - 243}

求解步骤

\frac{d x}{( x - 3 ) ^{5}}

(x - 3)^{5} = x^{5} - 15 x^{4} + 90 x^{3} - 270 x^{2} + 405 x - 243

= \frac{d x}{x ^{5} - 15 x ^{4} + 90 x ^{3} - 270 x ^{2} + 405 x - 243}

e x p an d, e^{2 x} + (1 - 2 x) e^{x} + x^{2} - 1

e x p an d (x^{3} + 2 x + 1)^{5}

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

e x p an d \frac{( a - 4 ) ( a + 6 )}{6}

e x p an d \frac{2 ( 3 + 4 z )}{3 w - 4 z}
