化简-2(1/5+5k)

解答

化简

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

- \frac{2 ( 25 k + 1 )}{5}

求解步骤

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

合并

\frac{1}{5} + 5 k : \frac{25 k + 1}{5}

= - 2 \cdot \frac{25 k + 1}{5}

使用分式法则:

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

= - \frac{2 ( 25 k + 1 )}{5}

\frac{d}{d q} ((R (q)) (R (q) (q^{4} + 1)^{5}))

e x p an d (2 sin (x) + 1) (cos (x) + 1)

e x p an d (5 x + 3)^{6} d x

e x p an d (6 x^{2} - 3 x^{3}) d x

e x p an d \frac{x - 4}{x ( x - 5 )}
