sqrt(121)
Enter square root or exponent statement:
Evaluate the following
√121
Term 1 has a square root, so we evaluate and simplify:
Simplify √121.
If you use a guess and check method, you see that 102 = 100 and 122 = 144.Since 100 < 121 < 144 the next logical step would be checking 112.
112 = 11 x 11
112 = 121 <--- We match our original number!!!
Therefore, √121 = ±11
The principal root is the positive square root, so we have a principal root of 11
Group constants
11 = 11
