lets go step by step
1. 3+2.64 (square root of 7)
2. Which equals 5.64
----------------------------------------------------------------------------
3.2-3.16 (square root of 10)
4. which equals -1.16
5. Now you should have 5.64/-1.16 (just divide those)

OpenStudy (anonymous):
fractions
OpenStudy (jacobbenvenutty):
So then just switch the answer to fractions

\[is the question \frac{ \sqrt{7} }{ 2} or \sqrt{7/2} ??\]
OpenStudy (jacobbenvenutty):
True i probably should have figured that out first..... what is it @naeegee?
