\frac{4 3}{π ^{2}} (23 x - 3)

\frac{24 x}{π ^{2}} - \frac{12}{π ^{2}}

求解步骤

\frac{4 3}{π ^{2}} (23 x - 3)

使用分配律:

a (b - c) = ab - a c

a = \frac{4 3}{π ^{2}}, b = 23 x, c = 3

= \frac{4 3}{π ^{2}} \cdot 23 x - \frac{4 3}{π ^{2}} 3

= 23 \frac{4 3}{π ^{2}} x - 3 \frac{4 3}{π ^{2}}

化简

23 \frac{4 3}{π ^{2}} x - 3 \frac{4 3}{π ^{2}} : \frac{24 x}{π ^{2}} - \frac{12}{π ^{2}}

= \frac{24 x}{π ^{2}} - \frac{12}{π ^{2}}
