I think it will only go to a number just so high, with your question being out of range. But for 4 to the 50th power, for example, you do this:

4 y^x (the key right below the OFF button) 50 and then =

So, 4^50 = 1.2676 30, or 1.2676 times ten to the 30th power.

Be sure to press your 2nd option (it is the yellow button)in order to get the correct answer. Example 4^81=3

Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

im not sure if this is what you want, any way that you can solve it in a TI calculater like this: Solve(3x^2-12x+19,x)
that will give you the answer for x

How do I raise the power of 30 on calculator?


If you are using an HP 12c or have the button on the calculator "yx" you first enter the number you wish to raise (y) then enter then the power (x). For instance to find 230 (2 to the power of 30) you input the number 2 then hit the enter key on the calculator, then input 30 and hit the yx button.

If you have another model of calculator the procedure may be similar or the buttons. Play around with it. By the way the solution to 2 raised to the 30th power is 1,073,741,824.

Hi i have the canon p170-DH and i cant subtract. example: 4-4= -8 not 0


Hi....by looking at the date you posted this question, you may have already found the answer, but just in case you haven't......the procedure for adding and subtracting on these calculators is completely opposite of a regular calculator. On a regular calculator, you would input 4 - 4 = 0. On these type of calculators, a number's positive or negative status is keyed in AFTER the number, instead of before it. Therefore, you input 4 + 4 - (notice you DO NOT input = at the end, but if you are in print mode, you will need to hit your total key, which looks like an asterisk, where the = would normally be, in order for the final value of your calculations to print on the paper tape.

Multiplication and division equations are done exactly as they are on a regular calculator....4 x 4 = 16.

Hope this helps. If you have your owners manual, it should also give you some examples of how to perform calculations with your calculator.

Inputing Scientific Numbers


If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....
