化简 x(1+x/(10))

解答

化简

x (1 + \frac{x}{10})

\frac{x ( 10 + x )}{10}

求解步骤

x (1 + \frac{x}{10})

合并

1 + \frac{x}{10} : \frac{10 + x}{10}

= x \frac{10 + x}{10}

使用分式法则:

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

= \frac{x ( 10 + x )}{10}

e x p an d (y - x + x y cot (x)) d x + x d y

s im pl i f y (x - y) (x + y)

\frac{\partial}{\partial x} ((f (x)) (x - 2)^{2})

e x p an d \frac{4 ( x ^{2} - 4 x - 1 )}{( x - 1 ) ^{2} ( x + 3 ) ^{2}}

e x p an d (11 - 44 i) (1 - 2 i)
