化简 g(m/z+(nx)/l)

解答

化简

g (\frac{m}{z} + \frac{n x}{l})

\frac{g ( m l + n x z )}{l z}

求解步骤

g (\frac{m}{z} + \frac{n x}{l})

合并

\frac{m}{z} + \frac{n x}{l} : \frac{m l + n x z}{l z}

= g \frac{m l + n x z}{l z}

使用分式法则:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{g ( m l + n x z )}{l z}

s im pl i f y 3 (x + \frac{1}{2})

s im pl i f y 2 (\frac{3 3}{2} + 3)

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

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

e x p an d (2 A x + B) e^{3 x} + e^{3 x} \cdot 3 (A x^{2} + B x)
