Answer:
SQRT formula
Step-by-step explanation:
I'm going to assume that do you need an Excel formula, in this case, you can use =SQRT(36) = 6 this is the same at 36^2 is The square root, we can find other numbers like =SQRT(100) = 10 this is the same at 10^2 but is the number is negative, we're going to receive an error.
For example =SQRT(-36) = #NUM!, we must use =SQRT(ABS(-36)) = 6.
