Answer 1

Do you mean \[3\sqrt{20}/2\]

Answer 2

yes

Answer 3

Okay this is simple, we must look at the 20 under the square root and say that it can be written as 4 time 5, then:
\[3\sqrt{4*5}/2\]
Next, the 4 comes out of the radical as a 2;
\[3*2\sqrt{5}/2\]
Then, we have:
\[6\sqrt{5}/2\]
Finally, the we can simplify this as;
\[3\sqrt{5}\]

Answer 4
