are these answers right?
1. ã-121 =
2. -2ã-144 =
3. ã-75 =
4. 5ãã-27 =
5. ã-6 * ã2 = ??
I will assume that your ã was supposed to come out as √
I disagree with #2
=-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.
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.
sorry, i see #5 THANK YOU!
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 ±
