Answer:
1
Explanation:
The square root of 1 is called 1.
In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4. The square root of 9 is 3, because 3 x 3 = 9.
The square root of 1 is 1, because 1 x 1 = 1. Therefore, the square root of 1 is simply called 1.
