(x^2+72)^{1/2}=9

(x^{2} + 72)^{\frac{1}{2}} = 9

x = 3, x = - 3

Solution steps

(x^{2} + 72)^{\frac{1}{2}} = 9

Square both sides:

x^{2} + 72 = 81

x^{2} + 72 = 81

Solve

x^{2} + 72 = 81 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions:

x = 3

True

, x = - 3

True

The solutions are

x = 3, x = - 3

x + 1 - x - 6 = 1

x^{0.2} (d - 6) = 0.3 d + 5 - 3 + 0.1 d

x - 1 = 4 x - 4

p + 16 + 4 = p

2 x + 1 + 2 x - 1 = 2
