展开

\frac{3 π ( 2 + 2 )}{32}

\frac{3 π}{16} + \frac{3 π}{16 2}

十进制

1.00556 \dots

求解步骤

\frac{3 π ( 2 + 2 )}{32}

乘开

3 π (2 + 2) : 6 π + 32 π

= \frac{6 π + 3 2 π}{32}

使用分式法则:

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

\frac{6 π + 3 2 π}{32} = \frac{6 π}{32} + \frac{3 2 π}{32}

= \frac{6 π}{32} + \frac{3 2 π}{32}

\frac{6 π}{32} = \frac{3 π}{16}

\frac{3 2 π}{32} = \frac{3 π}{16 2}

= \frac{3 π}{16} + \frac{3 π}{16 2}
