To solve the equation \( x^2 = 36169 \), we can take the square root of both sides.
The square roots of \( 36169 \) are \( 613 \) and \( -613 \) (since squaring either of these numbers gives us \( 36169 \)).
Therefore, the solution set is:
\[ { -613, 613 } \]
Thus, the correct response is:
\({ -613, 613 }\)
