So glad I found this site .... I have alot of questions, so please be patient with me :P ... so here goes, how do you denote the square root cubed?
Found this .... though.
$\displaystyle \sqrt{y=1}$

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

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

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

Thank you, you have been most helpful - Roux
