I only had to do problems 1, 2, and 5...The only one that i did not get was part c of number 5....

2. Hello, aikenfan!

$5c)\;\;\frac{\sqrt{3}}{\sqrt{2}}$
This must be rationalized .. .

Multiply top and bottom by $\sqrt{2}\!:\;\;\frac{\sqrt{2}}{\sqrt{2}}\cdot\frac {\sqrt{3}}{\sqrt{2}} \:=\:\frac{\sqrt{6}}{\sqrt{4}} \;=\;\frac{\sqrt{6}}{2}$

3. Thank you! Do the others seem correct?...I was having a lot of trouble with this before...

4. Hello, aikenfan!

The others are correct . . . Good work!

. . And thank you for showing your work.
