    put \[y=\sqrt{x}\] then x=\(\sqrt{y}\)

    hence \[\sqrt{x}\] is the inverse!

    How is x=√y prove that x^2 is the inverse?

    well if y is given in terms of x x in terms of y is the inverse

    This may sound like a dumb question, but the y turns back into an x, making root y into a root x making it x^2?

    yep that is because we always report a function in the form y=something
