展开

\frac{27 ( 8 + π )}{4}

54 + \frac{27 π}{4}

十进制

75.20575 \dots

求解步骤

\frac{27 ( 8 + π )}{4}

乘开

27 (8 + π) : 216 + 27 π

= \frac{216 + 27 π}{4}

使用分式法则:

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

\frac{216 + 27 π}{4} = \frac{216}{4} + \frac{27 π}{4}

= \frac{216}{4} + \frac{27 π}{4}

数字相除:

\frac{216}{4} = 54

= 54 + \frac{27 π}{4}
