    It is important to notice that \sqrt{3696}=4\sqrt{231}.

    Hence \sqrt{a}+\sqrt{b}=4\sqrt{231}.

    From this step you can choose any combination of root a's and root b's provided they add up to 4\sqrt{231}.

    I chose this combination:

    \sqrt{231}+3\sqrt{231}=4\sqrt{231}

    \sqrt{231}+\sqrt{2079}=\sqrt{3696}
