Решения:
3√(4+5)=1
3√9 = 1
1 = 1
√(3-2x)=x
3-2x = x^2
x^2 + 2x - 3 = 0
(x + 3)(x - 1) = 0
x = -3 or x = 1
√(x+3)=√(5-x)
x + 3 = 5 - x
2x = 2
x = 1
3√(3x^2-3)=3√8x
3√(3(x^2-1)) = 3√8x
√(3(x^2-1)) = √8x
3(x^2-1) = 8x
3x^2 - 3 = 8x
3x^2 - 8x - 3 = 0
(x - 3)(3x + 1) = 0
x = 3 or x = -1/3
√(x-1) = x + 1
x - 1 = (x + 1)^2
x - 1 = x^2 + 2x + 1
x^2 + x - 2 = 0
(x + 2)(x - 1) = 0
x = -2 or x = 1
Решения:
x = 1x = -3 или x = 1x = 1x = 3 или x = -1/3x = -2 или x = 1
