Depending on your version of the TI-30, you will either find a button with a y to the exponent of x or a button that is the carot (^) sign. you would type (1.0075)^(-240), where ^ is the appropriate button (y^x or just ^).

To the power of a negative


Hello,
Use the small (-) sign sometimes labelled [(-)] or [+/-] and put the whole exponent netween parentheses 18 [y to the x] [(] [(-)] 3 [)] . On some calculators you enter the small - signe after the value of exponent,
18 [y t x] 3 (-) [Enter] should give you 1.7146E-4
In summary the small minus sign; the whole negative exponent between parentheses.
Hope it helps.

EE button ("enter exponent" button) Retuns Wrong Value


Hello,
I dont think you got a lemon.
You acn always enter the powers of 10 as 10, [y^x], but is is less efficient than the EE key
This EE representation is a shortcut.
If you want 10 to the 5th power you just enter [2nd] [EE] 5 and the calculator displays 100000. Of course if you need any other number multiplying the power of ten you enter the following e.g. 2.677[x][2nd][EE]5.

You will not get any error with a positive exponent. But if your exponent is negative you should use the change signe key to the left of ENTER and symbolized by (-)

To avoid all errors I would use parentheses to enclose my exponent.

Here is how to explain the seemingly erroneous result

10 [EE] 5 ) (-) is interpreted by your calculator as 10x(10^(-5)) which evaluates correctly to 0.0001 because [EE] by itself stands for 10^ .


Hope it clarifies this point for you.

By the way some new calculators (Casio) don't have this EE key. Instead you find a key labeled x10^X .

Hope it helps

Exponents


the Xy button, 10 Xy 2 = 100 (10 x 10)

to do a neg exp you have two options, one use brackets if calculator has them.....

10 Xy (-2) = 0.01

or two inverse your number, ie: make 10 into 1/10th, use fraction entry on calculator.

1/10 Xy 2 = 10 Xy (-2) = 0.01

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
