Explicație pas cu pas:
I ⁶⁾5x - ²⁾1/3 I ≥ ³⁾1/2 <=>
I (30x-2)/6 I ≥ 3/6 <=>
I 30x-2 I ≥ 3
I 30x - 2 I = { 30x-2 , pentru x ≥ 1/15
{-30x+2 , pentru x < 1/15
30x-2 ≥ 3 => 30x ≥ 5 => x ≥ 1/6
-30x+2 ≥ 3 => 30x ≤ -1 => x ≤ -1/30
x ∈ (-∞ ; 1/30] ∪ [1/6 ; +∞)
Răspuns:
|5x - 1/3| ≥ 1/2
5x-1/3 ≥ 1/2, 5x - 1/3 ≥0
-(5x-1/3) ≥1/2, 5x - 1/3 <0
x≥1/6, x≥1/15
x≤ -1/30 , x< 1/15
x€[1/6;+∞)
x€(-∞;- 1/30]
x€(-∞;- 1/30] U [1/6;+∞)
