I'm simplifying Integer Exponents!! Can TI-84 do this?

I'm simplifying Integer Exponents and I have a TI-84 plus silver ed. and I'm wondering if I can do these right on the calculator, I have a feeling it won't as I can't figure out how to put variables (a,x, or y) in either. The problems look something like this: (3/xy^3)^-3 any help would be great.

Your feeling about this calculator not being able to do symbolic algebra is correct. It can only handle numerical values. You are better off using pen and pencil to perform the calculations you are talking about.

If you have a lot of symbolic calculations to do (algebra, calculus) you may want to consider looking at a calculator with a CAS (Computer Algebra System) such as the TI 89/Titanium, TI Voyage 200 PLT, the TI Nspire CAS, HP 40G/49G+/50G, Casio FX-Algebra, Casio CFX-9860G,GII etc.

Hope it helps.

Decimal exponents don't work

The EE (or x10^x on Casios) does give a syntax error if you use it with decimal exponents, but the expressions do calculate correctly if you use the full expression with the general power key. The EE key is a shortcut and may have been designed to accept only integer values for the exponents.
I tried that on Casio and the TI calculators.

I am trying to divide a power of 10 by and another number to a neg power of 10

For integer powers of 10 you can use the EE shortcut. [2nd][,] displays E.
For non-integer values of the exponent (such as -5.34) you must use the key sequence [2nd][LOG] (10^x) then enter your negative non-integer exponent.

I had an old TI-84 Plus Silver Edition calculator and when I put in exponents it would read as 9^2 (as an example). This calculator broke, so I got a new one. Now, when I do exponents, I push the 9...

How do I on a TI-84 Plus Simplify Fractions

Enter the fraction for example: enter 8/12.
The answer will be .666666
Then click Math (which is located under the Alpha button).
Click the ->Frac button (the first one).
It should come up as Ans->Frac.
Click Enter.
It should now read 2/3 which is 8/12 reduced.
Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition
