The value of square root of (√(-9)^2) is:
-9
9i
3
9
none of these
which one is the right answer?
So this is what I see:
(√(-9)^2)
The square root is over the everything, right? Something like sqrt( (-9)^2)? If so:
The answer is 9. First you square (-9), then you will have sqrt( 81), which is just 9.
However, just to clarify, if you have:
[ √(-9) ]^2, then the answer is just -9 because the square and square root cancels out. I hope that helps.
