    \sqrt{y=1}
    The "square root of x, cubed" could be written (\sqrt{x})^2. As long as x is positive, that is the same as "the cube of the square root of x", \sqrt{x^3}. And both of those can be written as x^{3/2}.

    Where did you find \sqrt{y=1}? That makes no sense. You take the square root of a number, not an expression. Perhaps you mean \sqrt{y+1} and just missed the "shift" key! But I don't see what that has to do with your question.

    Re: Newbie

    I was not clear in my question, I was looking for the format (LaTeX) to show \sqrt[3]{y+1}
    sticky fingers, Yes it should be \sqrt{y+1}

    Thank you, you have been most helpful - Roux
