This question looks a bit strange. Where did it come from?

$a\sqrt{b} + 6\sqrt{3} = \dfrac{14  8\sqrt{60}}{6\sqrt{20}  10\sqrt{12}}\ or$ $a\sqrt{b} + 6\sqrt{3} = 14  \dfrac{8\sqrt{60}}{6\sqrt{20}}  10\sqrt{12}?$

The same question was indeed posted, and an answer was given that assumed missing parentheses as per JeffM1's first expression. Although the desired form of a√b+6√3 wasn't achieved, Hezekiah seemed pleased with the answer given, so we never found out the fully correct version of the question.
