Best ResponseYou've already chosen the best response.0so it is always the numerator?

akash_809

Best ResponseYou've already chosen the best response.1no depends on what simplifies the root if 1root 3 was there in numerator and 1+root 3 in den the you would multiply num and den by 1root 3...since (1+root 3)(1root3)=13...using a^2b^2
