(x^2+45)^{1/2}=7

(x^{2} + 45)^{\frac{1}{2}} = 7

x = 2, x = - 2

Solution steps

(x^{2} + 45)^{\frac{1}{2}} = 7

Square both sides:

x^{2} + 45 = 49

x^{2} + 45 = 49

Solve

x^{2} + 45 = 49 : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions:

x = 2

True

, x = - 2

True

The solutions are

x = 2, x = - 2

2 = x + 1

x + x + 6 = 0

2 t + 7 = - 3

x, 6 + 5 x = x
