Best ResponseYou've already chosen the best response.2Sure, i can! Do you know how to simplify radicals?

Best ResponseYou've already chosen the best response.2To simplify radicals, you have to try to find a perfect square that fits perfectly into the number. So for the first one: \[\sqrt{27}\] the biggest perfect square that can fit into it is 9. So, the inside would simplify to be: \[\sqrt{9 \times 3} = 3\sqrt{3}\]

Best ResponseYou've already chosen the best response.0\[\sqrt75 = \sqrt5X15 = 5\sqrt5?\]

Best ResponseYou've already chosen the best response.2No, since neither 15 nor 5 are perfect squares. Here are the perfect squares: 1,4,9,16,25,36,49,64,81,100....

Best ResponseYou've already chosen the best response.2Ok since you want to get the biggest one that goes into there, start from the top of the list. Try seeing if 100 goes into 75 (obviously not), so just start from the smallest number after 75. 64,36,25,16,4,1. When you find the one that goes into 72, let me know.

Best ResponseYou've already chosen the best response.2Good! Now what times 25 is 75?

Best ResponseYou've already chosen the best response.2So thats what goes under the radical: \[\sqrt{75}= \sqrt{25 \times 3}= 5\sqrt{3}\] Right?

Best ResponseYou've already chosen the best response.0ok what do i do now multiply them together?

Best ResponseYou've already chosen the best response.2\[3\sqrt{3}+4\sqrt{2}5\sqrt{3}\] Is that what you have so far?

Best ResponseYou've already chosen the best response.2There are only 2 with the same base radical, so you can only simplify those

Best ResponseYou've already chosen the best response.0so i get \[8\sqrt3+ 4\sqrt2\]

Best ResponseYou've already chosen the best response.2Remember, it's 35, not 3+5
