Question about Texas Instruments BA-II Plus Calculator

1 Answer

Square root of more than 2

How do you crunch the number if I want to get 32's square root of 5? I can't find the key. All i can find from the BAII Plus calculator is the square root of 2. However, I need to calculate something a lot more complex than that.

How do i do square root on texas instrument ti-15


hi

if it a scientific calculator there should be a surd key ( look like a square root symbol, other way to get a square look for the "^" key that the exponent or power key do the follow type in the number be square rooted and press the "^" key and type "(1/2)" ( without the "" of course) and you will get the square root of your number. You can use the log and ln keys as well

type in your number you want square rooted and press the log or ln keys divide the result by 2 press the anti log key use might have press the 2nd key or shift key and press the log ( or 10^ key) or ln( or e^ key) the 10^ key and the e^ key change log to normal numbers

i.e.

square root 9

type 9 press log to get .954242509 for a result
divide by 2 to get .477121255 press the 10^ key to get
3 for a answer.

You can use the square-root function for any number, whether it's a perfect square or not. For example, to calculate the square root of 2, press SHIFT [square-root] 2 EXE .

[square-root] is on the x^2 key, just to the right of the ALPHA key.

I'm doing radicals I need to type an exponent into my calculator that goes before the square root not after. how do i do that (5) as an exponent square root of 32.....the answer is 2 but how do i type it...


Use the xth-root function to compute any root. It's the fifth entry on the MATH menu, which you can get by pressing the MATH key. The fourth entry on the same menu gives you the third root without needing the 3 to be specified.

For example, to compute the 5th root of 32, press 5 MATH 5 3 2 ENTER.

How to calculate a square root number after pressing the 2nd button? For example, one of the problems i was asked was, 105625 all in square root by pressing 2nd, x^2 105625) and enter. But I cannot find...


Are we discussing squares or square roots?

The square root is the 2nd function of the multiply key.

There is no square function on the keyboard. Instead, simply raise the number to the second power using the ^ key just above the divide.

How do i do a number 'to the power of 1/2 or 2/3? cheers Brad


Power 1/2 is the same as square root: You can use the square root key to the left of the square key.
Similarly power 1/3 is the cube root. You use the [SHIFT][Square root] key sequence.
Power 2/3 is the square of the cube root, or the cube root of the square.

More generally, you can use the universal power key, marked with X with a raised white rectangle. It is between X square and log.

Ex: Calculate 15^(2/3)
15 [X with raised rectangle] 2 [/] 3 [)] [=]; the result is 6.082
The last parenthesis closes the left parenthesis introduced by the calculator.
Alternatively you can use the cube root and the x-root selections available under the MATH menu.(selections 4 and 5)

How do you tak the square root of 64 or the 4 root of any other #


Hi shiny_diamon
Here is a picture of the powers and root functions of your calculator.
1.To calculate the cubic root of a number you use the key combination shown on line 5
Ex: Cubic root of 27
27 [2nd] [3 root x] [EXE]; Should get 3
2. You can use the general root key on line 7 [2nd][x Root y]
Ex: Cubic root of 125
125 [2nd][ x Root y] 3 [EXE] Should get 5
(-125) [2nd][x Root y] 3 [EXE]; Should get -5

3. You can also yse the general power key on line 6: [Y to x], but the degree of the root is entered as a fraction 1/3
Ex: cubic root of -125.
(-125) [Y to x]( 1/3) [EXE]; You should get -5

4. The [Y to x[ key is the one you use to obtain all other roots fourth, fift, tenth, n-th.
Ex: Fourth root of 256
256 [Y to x] (1/4) [EXE]: You should get 4

5. To extract the squqre root of a number you can use the key on the 3rd line [root x] or the general power key on line 6 with exponent 1/2
Exemple square root of 256
256 [Root x] [EXE] should give you 16
256 [Y to x] (1/2) [EXE] should give you 16 also

Hope that helps.

How to get the square root using a ti-30xa calculator?


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....
