展开-(4(11+sqrt(341)))/(11)

解答

展开

- \frac{4 ( 11 + 341 )}{11}

解答

- 4 - \frac{4 31}{11}

+1

十进制

- 10.71497 \dots

求解步骤

- \frac{4 ( 11 + 341 )}{11}

乘开

4 (11 + 341) : 44 + 4341

= - \frac{44 + 4 341}{11}

使用分式法则:

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

\frac{44 + 4 341}{11} = - (\frac{44}{11}) - (\frac{4 341}{11})

= - (\frac{44}{11}) - (\frac{4 341}{11})

去除括号:

(a) = a

= - \frac{44}{11} - \frac{4 341}{11}

数字相除:

\frac{44}{11} = 4

= - 4 - \frac{4 341}{11}

消掉

\frac{4 341}{11} : \frac{4 31}{11}

= - 4 - \frac{4 31}{11}
