On what? Do you mean 'how do you use latex to show radicals'?

Look at this code:

$$\sqrt{12}=2\sqrt{3}$$

This will yield:

$\sqrt{12}=2\sqrt{3}$

Is this what you're asking?

3. on what ??? nothing appear ??

I think that he ask about a sqrt question so I said to him nothing appear I mean what johnsy123 ask for

4. Hello, Amer!

masters gave you the right information.
Exactly what are you typing?

You can do other roots like this:

$$\sqrt[3]{8} =2$$

. . which produces: . $\sqrt[3]{8}=2$
