There are two because the square root of 16 for example is 4 or -4
Well, darling, the subset of real numbers for the square root of 169 is simply {13, -13}. It's not rocket science, honey. Just two numbers that, when squared, give you 169. Keep it simple, sweetheart.
-9 and 5 are two possible answers.
√144 < √165 < √169 12 < √165 < 13
Do you mean: What is the square root of (8 squared)? If so, there are two answers: 8 and -8. Or do you mean: What is the (square root of 8) squared? If so, there is only one answer: 8.
There are two answers: 20 and -20
There are two roots, both real: -13 and +13
