- \frac{38}{( 5 x + 1 ) ^{2}}

- \frac{38}{25 x ^{2} + 10 x + 1}

求解步骤

- \frac{38}{( 5 x + 1 ) ^{2}}

(5 x + 1)^{2} = 25 x^{2} + 10 x + 1

= - \frac{38}{25 x ^{2} + 10 x + 1}

e x p an d cos (4 (t + π))

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

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

e x p an d (2 + 33)^{15}

e x p an d \frac{x ^{6} - x ^{4} + x ^{2} - x - 1}{x ^{2} ( x - 1 )}
