    how many times does 2 go in to 18 ?

    i.e. what is \(18\div 2\) ?

    this is the easy part, the hard part is finding \(\sqrt{338}\)

    ok so \(\sqrt{w^{18}}=w^9\) is a start

    as for \(\sqrt{338}\) it turns out that \(338=13\times 13\times 2\) or \(13^2\times 2\) that means \[\sqrt{338}=\sqrt{13^2\times 2}=\sqrt{13^2}\sqrt{2}=13\sqrt{2}\]

    giving you a final answer of \(13w^9\sqrt{2}\)

    looks like A is \(13w^3\sqrt{2}\) which is not right
