What is most common power problem?

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents
Division with the same base - subtract the exponents
Exponent to an exponent - multiply the exponents
Negative exponent - 1 over the same number to the positive exponent
Zero exponent - anything to the exponent 0 is 1

Good luck,

We had a similar problem: enter a number like 6.02 [x10n] 23
The 23 is shown as exponent, in small, raised type. How to get out of the exponent is not obvious, but my daughter finally guessed it. The right side of the direction control (>) exits the exponent.

I have a TI-84. It gives me a syntax error when I try to enter problems with negative exponents.

Use the (-) key (just to the right of the decimal point key) instead of the - key when entering a negative number (not just exponents).
- is used to subtract one value from another. (-) is used to negate a value. - operates on two numbers, (-) operates on one.

Which exponent function?
To enter an exponent of ten, use 2nd [EE].
To raise ten to an exponent, use 2nd [10^x].
To raise e to an exponent, use 2nd [e^x].
To raise an arbitrary number to an exponent, use ^.

If i need to solve 1.0739229514 to the power of 3285 >>> it's telling me overflow! is there an option i can change in the meno to make it work? and sometimes it just gives me another...

If you have not read about the limitations of your calculator, then you have just reached them.
The result is 5.58100511329x10^(101).
If you want to have more digits the computer calculator will give you 31 decimal digits.
Your calculator gives an overflow error because the result exceeds what it can handle. The largest number that your calculator can handle is 1.x10^(100).
Personally I do not think you will ever have to raise a number to this power because no scientific or technical normal problem will require such a huge number of "significant digits".

Whenever I type in a negative number raised to an exponent, the calculator outputs a negative number! even for a question like -2^2. How do I fix this?

You're not raising a negative number to an exponent, you're negating a number raised to an exponent.

If you want to raise -2 to the second power, you need to enter it as
( (-) 2 ) ^ 2

Without the parens, what you're getting is the equivalent of -(2^x)

To write 50 exponent in math mode, type your number then hit the key that has (x with the solid white exponent key). It's between the (x squared key) and the (log key) then you can enter the number 50 for your exponent. You can also hit the (x squared key) delete the 2 exponent and type in the exponent you want.

Correct me if I'm wrong but are you asking what an exponent is? If you are an exponent is the small number to the upper right corner of a number. the larger number is multiplied by itself by the smaller number (ex. large 4 and small 5= 4x4x4x4x4= 1024)
