are these answers right?
1. ã121 =
iã11
2. 2ã144 =
2iã144 =
2i*12=24i
3. ã75 =
i=ã75 =
iã5sq*3 =
5iã3
4. 5ãã27 =
5iã27 =
5iã3sq*3 =
15iã3
what about
5. ã6 * ã2 = ??

Reiny,
I will assume that your ã was supposed to come out as √
I disagree with #2
2√144
= 2i√144
= 2i(12)
=24i (you lost the negative sign)
Also I will assume that in#4, the double square root was a typo
If so, then the rest were correct.

Reiny,
#5
√6√2
= i√12
= 2i√3

teri,
yes to #4 i don't know how they symbols don't come out when i type them one way.
Can you help with #5? I didn't get it.
Thank you.

teri,
sorry, i see #5 THANK YOU!

For a √ sign 
Reiny,
If you are on a Mac...
hold down the "Option" key and press V, then release to get the √
There are a whole bunch of those shortcuts, like hold down the "Option" key, and press p to get π
on a PC , I hold down the Alt key, and while holding it down, pres 251 on the number pad, then release. You should get a √ sign
Again just like on a Mac, you can experiment with these on a PC to get different symbols
e.g. try "Alt" 241 to get ±
