(x^2+21)^{1/2}=5

(x^{2} + 21)^{\frac{1}{2}} = 5

x = 2, x = - 2

Solution steps

(x^{2} + 21)^{\frac{1}{2}} = 5

Square both sides:

x^{2} + 21 = 25

x^{2} + 21 = 25

Solve

x^{2} + 21 = 25 : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions:

x = 2

True

, x = - 2

True

The solutions are

x = 2, x = - 2

x, s (x) = - 14 - x

4 x + 5 = 1 + 7

3.25 = \frac{4}{x ^{2} - 1}

- 5 p = 24 - p
