i would say the ^2 and the √ cancel each other out leaving -9. But as with every reply i post, im not confident lol
I just typed it into the calc and it reads 9. So basically, im useless lol
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.
