(-(sqrt(5)))/3 <= x<e

解答

\frac{- ( 5 )}{3} \leq x < e

- \frac{5}{3} \leq x < e

间隔符号

[- \frac{5}{3}, e)

十进制

- 0.74535 \dots \leq x < 2.71828 \dots

求解步骤

\frac{- ( 5 )}{3} \leq x < e

\frac{- ( 5 )}{3} = - \frac{5}{3}

- \frac{5}{3} \leq x < e

8.1 < y < 8.2

- 3 < x - 1 \leq 5

2 x - 3 < x + 1 < 4 x + 7

2 x - 8 < x < x + 4

- 3 + x < 8 \frac{x}{3} + 2 < \frac{14}{3 + 2 x}
