Sure, i can! Do you know how to simplify radicals?

zaynahfBest ResponseYou've already chosen the best response.2
To 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: \[\sqrt{9 \times 3} = 3\sqrt{3}\]

so i can get \[\sqrt16X2 = 4\sqrt2 ?\]

\[\sqrt75 = \sqrt5X15 = 5\sqrt5?\]
 one year ago

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

lol i'll guide you through

Ok 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.

64 goes into 75 evenly?

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

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

ok what do i do now multiply them together?
 one year ago

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

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

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

Remember, it's 35, not 3+5
