yes, even after just guessing (because clearly, you did not bother to grab your calculator)
121 = 11 • 11 = 11²
√121 = √(11²) = ± 11
just to note the details,√121 = 11
just because (-11)^2 is also 121, that does not mean that it is "the square root" of 121
To find the square root of a number, you need to find a number that, when multiplied by itself, gives the original number. In this case, the original number is 121.
