Enter square root or exponent statement:
Evaluate the following
√9
Term 1 has a square root, so we evaluate and simplify:
Simplify √9.
If you use a guess and check method, you see that 22 = 4 and 42 = 16.Since 4 < 9 < 16 the next logical step would be checking 32.
32 = 3 x 3
32 = 9 <--- We match our original number!!!
Therefore, √9 = ±3
The principal root is the positive square root, so we have a principal root of 3
Group constants
3 = 3
Build final answer:
3
