Exponents of 10 are entered by pressing [2nd][X^-1] (EE).

For powers of any base, enter the base, press the [^] (below PI) then enter exponent. Use the (-) white key if exponent is negative.

Press the (-) key located just to the right of the decimal point key before entering the exponent. Don't use the - key to the right of the 6 and 9 keys, this is to subtract one number from another. The (-) key is for negating numbers.

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 ^).

I think what you did was use the minus sign instead of the negative sign, on that calculator, the two are not interchangeable. I purposely used the minus sign just now and also got a syntax error, but it looks like it works with the negative sign (-) located under the 3 button.

Make sure you use the (-) key to the right of the decimal point key for negative values, not just exponents. The - key between the multiply and add keys is for subtracting one value from another.

Type in the mantissa, then the EE key (for Enter Exponent) above the 7 key, then the exponent. If it's a negative exponent, press the (-) key to the right of the decimal point before entering the exponent.

You need the [EE] key to enter powers of 10 exponents.

You need the change sign key [+/-] key.

You need the [LOG] key.

pKa: 6.5 [EE] [+/-] 5 [LOG] [+/-]

There are two change sign: The first (either before or after the exponent 5), the last is entered after you press the log key , so as to negate (make negative if result is positive, and make positive is result is negative) the value.

The result should be 4.1870866 or 4.19
