Question

X^2 = 121

Answer 1

11

Answer 2

Try take square root of both sides.

Answer 3

Then you would have \(X = \pm\sqrt{121}\)

\(\pm\) because \(X\) was squared, so \(X\) could be either positive or negative.

Answer 4

Answer is not just 11. @iamabarbiegirl

Answer 5

yeah thats what i did \[\sqrt{121} = 11 \]

and 11^2 = 121 how is it wrong?

Answer 6

"Not just 11", as in 11 is not the only answer.

Answer 7

\(X\) could be \(-11\), because \((-11)^2 = 121\)
