Question

Решите уравнения
1)х^2=36
2)х^2=1,96
3)х^2=23
4)х^2=37
5)х^2=-29
6)3х^2=48

Answer 1

1) x^2 = 36;
x = -6 ∪ x = 6.

2)x^2 = 1,96
x = -1,4 ∪ x = 1,4.

3)x^2 = 23
x = -√23 ∪ x = √23.

4)x^2 = 37
x = -√37 ∪ x = √37.

5)x^2 = -29
нет действительных решений.

2)3x^2 = 48
x^2 = 16
x = -4 ∪ x = 4.
