Question about Texas Instruments TI-30 XIIS Calculator

How do you use x of square root on a ti-30x

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

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.

28

square root (28)+1 = 6

Factors

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,

Paul

The calculator is able to display fractions and certain irrational number as radicals. However there is the twosided arrow key to

toggle between exact and approximate (decimal).

Here is a screen capture from the manual to give you some more informations.

Option 1: Find the button that looks like "" and then type "110.5" in the parenthesis. Hit enter.

Visual: ?(110.5)

Option 2: Set "110.5" to the "1/2" using the " ^ " button. Hit enter.

Visual: 110.5 ^ (1/2)

Visual: ?(110.5)

Option 2: Set "110.5" to the "1/2" using the " ^ " button. Hit enter.

Visual: 110.5 ^ (1/2)

You can download several Guidebooks and references for the TI-30 family from the manufacturer's web site at http://education.ti.com/educationportal/downloadcenter/SoftwareList.do?website=US&tabId=2&paneId=18

One way is you get square root by raising to the (1/2) power. For example square root of 16 is

16^(1/2).

You can use this method to get the other "roots" as well e.g. 1/3, 1/4, etc.

16^(1/2).

You can use this method to get the other "roots" as well e.g. 1/3, 1/4, etc.

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....

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.
