Just simplify radical then simplify the entire expression.

Answer 4

well I am working on it now

Answer 5

\[\sqrt{28}=2\sqrt{7}\]

Answer 6

i think you just rationalise the numerator...

Answer 7

fine

Answer 8

\[(-4*\sqrt{7})/3\]
-3.52766

Answer 9

@nitz Why did you do all the work for ctccbuggs?

Answer 10

You wasn't suppose to give the answer, lol...

Answer 11

FYI: I do not need anyone to do all the work for me but I need someone to break it down for me so I can understand the problem. So asking me questions about the problem is not helping me. Show me how to do it by break it down will. Okay

Answer 12

Thanks Nitz, but can you BREAK IT down for me please. So I can understnd better.

Answer 13

√28 = √(7·4) = √7√4 = 2√7

Does this help you?

Answer 14

I understand that part but how do the -2 and 3 come in to complete the problem. I am an online student and my book do not break down that part.

Answer 15

So you got \[\sqrt{28} = 2\sqrt{7}\]
Now put this value in the actual question
\[-2\sqrt{28}/3 = -2(2\sqrt{7})/3 = -4\sqrt{7}/3\]

Answer 16

Thanks

Answer 17

welcome :-)
