You will have to use the X^y function, which is on top of the fourth key from the right of the rows containing the big buttons (on top of the multiply symbol).

Now let us say you arte interested in 2^ 5 = 32, you type two and then the shift key and then the X^y key, followed by the number 5 and enter. You should see 32 on the screen

How do i enter an exponent on the


It depends on the base of the power function.
For exponential function use [SHIFT][LN] (e^x) followed by the exponent value. If exponent is negative use the change sign +/- key before exponent.
For a general power, type in the base (number), then press the [Y^x] key followed by the exponent.
For a power of 10, use the [Exp] key. Careful here. For example to enter 1.6x10^(-19), type in 1.6, press the [Exp] key, then the change sign key +/- and the exponent. Press [=]
1 . 6 [Exp] +/- 19 [=]

NOT SHOWING NEGATIVE EXPONENTS


Try this if you have parenthesis.
(5*10^-9)*(4,4*10-9).

I'm assuming you are using a comma as the decimal deliminator and are located in Europe. (4,4 instead of the English 4.4).

Your working example also has no spaces between the elements of yoyr formula. Watch this.

What do I press to get the exponent 3 on BA II PLUS? Thanks


To raise a value to a power, use the y^x key located just above the 9 key. For example, to raise 2 to the third power, press 2 y^x 3 =

Unlike most calculators, there is no dedicated key for decimal exponents. You will have to use the above procedure to raise 10 to an exponent.

Needing help with addint the power of into calculator


Use the key labeled times 10 to power X, the one between the decimal dot ant the Ans keys, in the middle of the bottom row of keys.
10 to the power 0 is entered as 1. [x10^X] 9 or simply [x10^X] 9
To enter negative exponents use the change sign key [(-)] just above the [RCL] key
10 to -9 is entered as [x10^X] [(-)] 9 result is shown as 1x10-9.

To solve 10 raised -3, to be done with cal., answer in the display ought to be .001


The calculator has several decimal display formats: FIX, SCI, NORM and ENG.
Here are examples of calculations with different formats and how to set them.

It may be a good idea for a user to get accustomed to the scientific display format, because it is the one most calculators adopt when the result to be displayed is too large or too small--when there are not enough places on the screen to display the result.

To help you with the power of 10 notation

1 billion =1000 000 000 =1 E 09 (9 zeros after 1 >> exponent 9)
1 million=1 000 000 = 1 E 06 (6 zeros after 1 >> exponent 6
1 thousand= 1000 =1 E03 (3 zeros after 1 >> exponent 3)
One= 1 = 1 E0
One tenth = 1/10 =0.1: the 1 is ONE position after the decimal mark>> exponent -01
One hundredth =1/100 =0.01 the 1 occupies the 2ND position to the right of the decimal point, exponent -02
etc.
1/1000 =0.001 = 1E-03
1/10000=0.0001=1E-04 (1 in 4th position to the right of decimal mark)
1/1000000=0.000001 = 1E-06 (1 in 6th position to the right of decimal mark)

1E-09 =0.000000001 : the 1 is in the 9th position to the right of decimal mark.

Entering a problem


Hi Loringh,
see, high exponents are +ve powers, while low exponents are -ve powers.
e.g. for 1200000=1.2X10^6=1.2E+6 (high exponents)
for 0.0000000012=1.2X10^-9=1.2E-9 (low exponents)
I think so easy ?

Thanks
