To solve the equation \( x^2 = \frac{36}{169} \) using inspection, we can take the square root of both sides.
First, we rewrite the equation:
\[ x^2 = \frac{36}{169} \]
Taking the square root of both sides, we have:
\[ x = \pm \sqrt{\frac{36}{169}} \]
We can simplify this:
\[ x = \pm \frac{\sqrt{36}}{\sqrt{169}} = \pm \frac{6}{13} \]
Thus, the solutions are:
\[ x = \frac{6}{13} \quad \text{and} \quad x = -\frac{6}{13} \]
Therefore, the correct solution set is:
\[ \left{-\frac{6}{13}, \frac{6}{13}\right} \]
So the correct response is:
{−6/13, 6/13}
