Best ResponseYou've already chosen the best response.0Sqrt(27) + sqrt(108) + sqrt(27) + sqrt(108) Then you need to simplify each radical Do you know who to do that? sqrt(27) = 2sqrt(3) What is sqrt(108) =

Best ResponseYou've already chosen the best response.0No.. you can't do it that way. If they want "exact" Have you been working on radicals and simplifying them?

Best ResponseYou've already chosen the best response.027 = 3 * 3 * 3 108 = 2 * 54 = 2 * 2 * 27 = 2 * 2 * 3 * 9 = 2 * 2 * 3 * 3 * 3 So 108= 2 * 2 * 3 * 3 *3 Doyou understand this?

Best ResponseYou've already chosen the best response.0OK the way you simplify a radical is  circle groups of two that are alike. FOr example. 27 = 3 * 3 * 3 you would circle the first two 3's and they go outside the sign with the uncircled 3 left underneath. sqrt(27) = 3sqrt(3) 108 = 2 * 2 * 3 * 3 * 3 you would circle the 2's and the 3's and there would be one 3 left over. You multiply things that come out, and multiply things that are left underneath. sqrt(108) = 6sqrt(3) So 3sqrt(3) + 6sqrt(3) + 3 sqrt(3) + 6sqrt(3) = 18sqrt(3) That is your answer...
