The answer is 2x^2 * 3âˆš2 (or ^2/3, I don't know how to indicate that specifically using keys but the 3 is inside the v of the square root symbol)

But my question is how I would multiply that expression to get the answer? Any math calculator or guide I consult seems to say that you can't multiply the expression, but it's clearly happening here.

Thank you very much!
