# Can you add a radical with a whole number 4 + 2sqrt3?

No, you can't.

You can't even add different radicals, like $\sqrt{2} + \sqrt{3}$ and if the radicals are of different power, you can't even add those, so

$\sqrt{2} + \sqrt[3]{2}$ stays as is.

The most you can do with your example is take the $2$ 'out of the brackets', but only if that's useful for further calculations, like:

$4 + 2 \sqrt{3} = 2 \cdot \left(2 + \sqrt{3}\right)$
