If you mean an exponent of ten, use 2ND EE (located on the SIN key just above the 7). If you're raising an arbitrary number to a power, use the ^ key just above the divide.

In either case, if the exponent is negative, make sure you use the (-) key to the right of the decimal point instead of the - key.

### 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.

### Exponent function keys

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 ^.

### HOW CAN I GET AN EXPONENT FROM TI-84 EX: B

You cannot use a letter as an exponent, unless you stored a numerical value in memory B (EX: 3 [STO>] [ALPHA] B stores value 3 in B)
For any numerical value of exponent ( positive, negative, integer, fraction, what have you) you use the general power key, marked with a caret [^] under the [CLEAR] key.

Example: To enter 15 to power 5
Type in 15
Press [^] key
Type in the value of the exponent (5) and press [ENTER]
You get 759375 as result.

### How do you find a number's tenth root on a TI BA2 Plus calculator?

Use the universal power key marked [Y to x] or [Y^x].
This key allows you to calculate powers with arbitrary exponents.
To obtain the roots to any degree you make use of the fact that n-th root of a number X is equivalent to the number X raised to the power 1/n

10th root of X = X raised to the power 1/10
10 th root of 2345 = (2345)^ (0.1)
For this case
2345^(0.1)=2.172772644
