\frac{2 a}{2 y}

\frac{a}{y}

求解步骤

\frac{2 a}{2 y}

数字相除:

\frac{2}{2} = 1

= \frac{a}{y}

e x p an d - \frac{5 a ^{2}}{- a}

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

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

e x p an d (u v^{2} + w^{3}) (u + v e^{w}) (3)

e x p an d \frac{( 3 y - a ) ^{3}}{27}
