    multiply the fraction by - sqrt3/-sqrt3 that is \[\sqrt{3} / \sqrt{3}\] that gives you \[8 \sqrt{6} /3\]

    no the final answer is 8 multiplied by square root of 6 the whole thing over 3 my answer is the final answer because you are multiplying by root 3 / root3 which is 1 that does not change the value of the fraction so the answer i typed is the final answer
