解答

展开

(7 - 3 ln (2)) \frac{3 π}{2} - (7 - 3 ln (2)) π

\frac{21 π}{2} - \frac{9 π ln ( 2 )}{2} - 7 π + 3 π ln (2)

十进制

7.72919 \dots

求解步骤

(7 - 3 ln (2)) \frac{3 π}{2} - (7 - 3 ln (2)) π

= \frac{3 π}{2} (7 - 3 ln (2)) - π (7 - 3 ln (2))

乘开

\frac{3 π}{2} (7 - 3 ln (2)) : \frac{21 π}{2} - \frac{9 π ln ( 2 )}{2}

= \frac{21 π}{2} - \frac{9 π ln ( 2 )}{2} - (7 - 3 ln (2)) π

乘开

- π (7 - 3 ln (2)) : - 7 π + 3 π ln (2)

= \frac{21 π}{2} - \frac{9 π ln ( 2 )}{2} - 7 π + 3 π ln (2)
