解答

展开

\frac{π ( 17 17 - 1 )}{96}

\frac{17 17 π}{96} - \frac{π}{96}

十进制

2.26105 \dots

求解步骤

\frac{π ( 17 17 - 1 )}{96}

乘开

π (1717 - 1) : 1717 π - π

= \frac{17 17 π - π}{96}

使用分式法则:

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

\frac{17 17 π - π}{96} = \frac{17 17 π}{96} - \frac{π}{96}

= \frac{17 17 π}{96} - \frac{π}{96}
