How many integers satisfy the condition 0≤23[x]≤1
[x] takes only integer values. 0≤23[x]≤1 ⇒0≤[x]≤1.5
So the values [x] can assume are 0 and 1.
Therefore, the integral solutions for this inequality are 0, 1
How many integers satisfy the condition |x| ≥ 2 and |x|≤ 6
How many integers satisfy the condition |x|≤−5
How many real numbers satisfy the condition 0 ≤ 23[x]≤ 1 ?
