what does square root x^16 equal?
sqrt(x^16) is x^8.
As you can see, x^8 x^8 = xxxxxxxx xxxxxxxx which equals x^16
I don't know why Cortesalondra28 deleted my answer to the question and sayid it was wrong..
the square root is of 16 is 4, not 8.
While your statement XXXXXXXX XXXXXXX*X does equal x^16, that is not what the question is asking.
