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

99 + 702

十进制

197.99494 \dots

求解步骤

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

(2 - 1)^{5} = 292 - 41

= \frac{2 + 1}{29 2 - 41}

\frac{2 + 1}{29 2 - 41}

有理化:

99 + 702

= 99 + 702

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

e x p an d \frac{1}{3 ( 5 a - 2 b )}

e x p an d lo g_{10} (4 \frac{y ^{3}}{20 x ^{5}})

\frac{\partial}{\partial x} ((z) (x^{2} e^{y} + 10 y))
