Answer 1

To solve the equation \( x^2 = 81 \) by inspection, we can think about what number squared gives us 81.

The two numbers that satisfy this equation are:

• \( 9 \) because \( 9^2 = 81 \)
• \( -9 \) because \( (-9)^2 = 81 \)

Thus, the complete solution set is:

\({ -9, 9 }\)

So the correct response is:

\({-9, 9}\)
