化简 8(3/2+3x)

解答

化简

8 (\frac{3}{2} + 3 x)

24 x + 12

求解步骤

8 (\frac{3}{2} + 3 x)

合并

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

= 8 \cdot \frac{6 x + 3}{2}

使用分式法则:

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

= \frac{8 ( 6 x + 3 )}{2}

数字相除:

\frac{8}{2} = 4

= 4 (6 x + 3)

展开

4 (6 x + 3) : 24 x + 12

= 24 x + 12

e x p an d \frac{π ( 3 + 3 2 )}{4}

e x p an d 2 (2 + 3)

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

e x p an d (x^{2} - \frac{1}{x ^{4}})^{6}

e x p an d ln^{2} (x - 2) (e^{x - 3} - 1) sin (\frac{π x}{3})
