Answer 1

To solve the equation $x^2=36169$ by inspection, we can find the square root of both sides of the equation.

Taking the square root, we have:

$$x=\pm \sqrt{36169}$$

Now, we need to find $\sqrt{36169}$. By inspection or by calculating, we find that:

$$\sqrt{36169}=189$$

Thus, the solutions to the equation are:

$$x=189\text{and}x=-189$$

This means the correct solution set is:

{ -189, 189 }

So the correct response is: {−189, 189}.
