If you can't find the square root sign you could enter it like:
4^(1/2)=2 and 16^(1/2)=4 just what #your look for the square root of just take to the ^(1/2)
I'd like to give the key reference for the square root sign but, I loan my calculator to a student

Is it possible to calculate factors using a TI-30x IIS

I believe factors can be calculated on any basic calculator.

Starting with 1, increasing by 1 until you get to square root (number) + 1

Let's do an example.

square root (28)+1 = 6
1, 28/1=28
2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal)
3, 28/3=9.33333 - not a factor - doesn't go in evenly
4, 28/4 =7
5, 28/5=5.6 - not a factor - doesn't go in evenly
6, 28/6=4.66666 - not a factor
So now we can list our factors - 1, 28, 2, 14, 4, 7
Putting them in order, we get 1, 2, 4, 7, 14 and 28.

Good luck,

Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....
