ARUNAV from DPS VINDHYANAGAR, VINDHYANAGAR
Class : Class 9
You all may have done squaring on both sides. Now what you got it a² b²-2(because ab of third term cancel out)=64/9(8/3 square)(we are supposing a as root 3 x and b as1/ root 3 x)As the identity for (a b)² is a² b² 2(remeber ab of 2ab cancels out in all steps in this question),we need to add 4 on both side, and then square root the whole equationWe get a² b² 2=100/9. And on rooting, as both 10/9 and -10/9(if you are having problem understanding this then you must read some 9th class chapter's basic.)So option c is the answer
