(\frac{2 x}{6}) + (\frac{5}{3 x})

\frac{x}{3} + \frac{5}{3 x}

求解步骤

(\frac{2 x}{6}) + (\frac{5}{3 x})

去除括号:

(a) = a

= \frac{2 x}{6} + \frac{5}{3 x}

消掉

\frac{2 x}{6} : \frac{x}{3}

= \frac{x}{3} + \frac{5}{3 x}

e x p an d \frac{10 x ^{2}}{2}

e x p an d \frac{( 3 x ^{2} + 4 )}{( x + 2 ) ^{2} \cdot ( x ^{2} + 25 )}

e x p an d 4 + x^{3} (12 x^{2} y^{3} + 3 x^{5} y^{3} - 1)

e x p an d (a + b + c^{^{'}}) \cdot a \cdot b \cdot c

e x p an d (cos (3 x + 1) sec (2 x + 1)) (12 x (2 x^{3} + 1)^{2})
