Either the square and square root cancel and leave you with -1 or square -1 to one and sqrt 1 = 1
English
-
The power affects 1, not the minus sign, thus the answer is i
-
Wouldn't that be sqrt(-(1^2) and not what you put in the title?
-
Im pretty sure (-1^2) is the same thing
-
It's not. That indicates the -1 is squared, which is -1*-1=1
-
No if it was (-1)^2 then it would be 1 but (-1^2) and -1^2 are the same thing, one just has parentheses
-
In standard mathematician writing, the expression -1^2 is referring to (-1)^2. If you want to refer to the one being squared, then made negative, the standard expression is -(1^2). Don't believe me? Punch it into any TI calculator and report the results. It should be as I described it.
