√x=x^2 is the equation correct

This equation is incorrect.

Step-by-step explanation:

The sqrt(x) does not equal x squared.

You can rewrite a square root to be to the one-half power.  See if this looks correct:

x^(1/2) ?= x^2

No of course these aren't equal.  Hence, this equation is incorrect.
