√49 ⋅ 81 ⋅ √24 = 7 ⋅ 9 ⋅ 2√6 = 63 ⋅ 2√6 = 126√6 ≈ 504
√125 ⋅ √32 - 51/2 = √(5³ ⋅ 2⁵) - √5 = √(5³ ⋅ 2³ ⋅ 2²) - √5 = 5 ⋅ 2 ⋅ √5 ⋅ 2 - √5 = 10 ⋅ 2 ⋅ √5 - √5 = 20√5 - √5 = 19√5 ≈ 10
(√6 - √11 - √6 + √11)² = (√6 - √11 + √6 - √11)² = (2√6 - 2√11)² = (2(√6 - √11))² = 4(6 - 2√(66) + 11) = 4(17 - 2√(66)) = 68 - 8√(66) ≈ 22
√(√17 + 3) ⋅ √(√17 - 3) = √(17 - 9) = √8 = 2
√(√6 + 2√5) ⋅ √(√6 - 2√5) = √(6 - 4 ⋅ 5) = √(-14) = 1
√(x - 2) = 4 => x - 2 = 16 => x = 18
√(5 - x) = √(x - 2) => 5 - x = x - 2 => 2x = 7 => x = 3
√(2x + 4) = x - 2 => 2x + 4 = (x - 2)² => 2x + 4 = x² - 4x + 4 => x² - 6x = 0 => x(x - 6) = 0 => x = 0, x = 6
√x - √(x - 5) = 1 => √x = 1 + √(x - 5) => x = 1 + 2√(x - 5) + x - 5 => 4 = 2√(x - 5) => 2 = √(x - 5) => 4 = x - 5 => x = 9
√(x - 3) < 2 => x - 3 < 4 => x < 7, x ≥ 3 => 3 ≤ x < 7
√(4 - 5x) ≥ 8 => 4 - 5x ≥ 64 => -5x ≥ 60 => x ≤ -12
