X - 4 = 169
x = 169 + 4
x = 173


--------------------------
Assuming you made a mistake in typing the problem, and your topic is about extracting the roots as solution to quadratic equation:

(x - 4)² = 169

 ( \sqrt{x-4}) ^{2} = \sqrt{169}

x - 4 = 13

x = 13 + 4

x = 17

Check:
(17 - 4)² = 169
(13)² = 169
169 = 169
