Make sure you use the +/- key (located just right of the decimal point key) to enter a negative number. For example, to raise 3 to the -2 power, press 3 y^x 2 +/- =

SOURCE: No decimal display on TI BA-II calculator

Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

SOURCE: how do u make BA

Press 2nd [FORMAT] and select the number of digits you want to the right of the decimal point or 9 for floating, which displays the non-zero digits. Be aware that if the number has more than ten digits then it will round to ten digits.

Good morning Cesar

The guide for you calculator can be found here

https://education.ti.com/en/us/guidebook/details/en/ADF11FB65B284B6195B0A7E9502784BA/baiiplus If you go to page 12, you'll see that this operation, for 42.2 to the 1.56 power would be done with [42.2] [Y^X][1.56][=]

You could also do this with [42.2][ln][X][1.56][=][e^X] to do it with logarithms (which is how the calculator is doing it as well).

Happy New Year!

Sorry, but the BA-II doesn't do fractions. It only works with decimal numbers.

Feb 23, 2014 | Texas Instruments BA-II Plus Calculator

The same way you raise a number to a non-fractional power, using the y^x button. For your example, press

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

Sorry, but there is nothing wrong with the exponential notation on your calculator. There is however a misunderstanding from your part on the priority rule of operations.

The sequence 0.030377/6.022x10^23 is interpreted as (0.030377/6.022)x10^23 while you wanted 0.030377/(6.022x10^23), dividing by Avogadro's Number.

How to fix it. Enter the power of 10 exponent (10^23) using the EE key. In other words Avogadro's Number should be typed in as 6.022 [EE]23. If you do not have the EE key you must use parentheses to enclose the whole number (6.022x10^23) or use the division key twice /6.022/10^23

On a calculator a sequence a/bxc where both operations have the same level of priority is executed from left to right.

Hi,

To access the exponential function press**[2nd] [e^x]**

To type your expression:

**45 [*] [2nd][ e^x] [( ] .03 [*] .75 [ ) ]**

Do not forget the parentheses.** If need be, press [=].** The result should be 46.02397654

Hope it helps.

Thank you for rating this solution.

Hello,

To use the exponential function,**you must enter the number then press [2nd][e to the x] or [e^x] for short.**

e^(-0.1) is entered as (-)0.1 [2nd][e^x], where**(-)** is the change sign key

You will need to use extra parentheses to avoid errors.

**20 - 18*( (-)0.1 [2nd][e^x] ) [=]**

The Minus sign between 20 and 18 is the regular one. The** (-) **before the 0.1 is the change sign key **(-)** or sometimes labeled** +/-**. The asterisk is the multiplication sign.

Hope it helps.
