Answer:
6i is the square root
Explanation:
The square root of a negative number means there are no real numbers we can use, so it must be an imaginary number. The square root of 36 is 6, the square root of any negative has (i) or an imaginary number in it. As (i) squared is equal to -1. So 6i squared is 36(-1) or -36. Making the answer 6i.
