-------------------
138.
-------
1)
√x ≥2 ⇔ x ≥ 2² ⇔
x∈[2 ; ∞).
2)
√x < 5 ⇔ 0≤ x <5² ⇒
x∈ [0 ; 25) .
3)
∛x >3 ⇔x >3³ ⇒
x∈ [27 ; ∞ ).
4)
∛x ≤ 2 ⇔x ≤2³ ⇒
x∈ ( -∞ ; 8 ].
----------------------------------------
139.
-------
1)
√(x+1) >2 ⇔x+1 >2² ⇔ x > 4 -1 ⇔
x ∈ (3 ;∞).
2)
√(1-x) ≤4 ⇔ 0 ≤ 1- x ≤ 4² ⇔ -16 ≤ x -1 ≤0 ⇔ -15 ≤ x ≤ 1 ⇔
x ∈ [-15;1].
3)
√(3x+1) ≥1 ⇔ 3x+1 ≥1² ⇔ 3x ≥0 ⇔ x ≥ 0 ⇔
x ∈ [0;∞].
4)
√(2x-1) < 3 ⇔ 0 ≤ 2x -1 < 3² ⇔ 1 ≤ 2x < 3² + 1⇔ 1/2 ≤ x <5 ⇔
x ∈ [0,5;5).
