The rightmost column, right above the divide button and below the CLEAR button. If that button doesn't say "^" then you've got a mismarked keyboard.

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 don't know what buttons to hit to put exponents into my TI-68

Write the expression in radicant exponent the given is square root of 81 what is the answer and the solution.

I come up with 3. (81^(1/2))^(1/2)=3. the Simplest form. I used 81^(1/2) because, 81 looks like 81 to the first power, instead of a fraction.

I need to learn how to turn off exponents - I am dividing 35 by 360000 I want the regular decimal number, not the exponent factors. Help! Thanks! New to my TI-81. Jessi

You just select [MODE] use your left arrow if needed to select [Norm]. You might want to look at the other mode settings to select the ones that apply to the type of math your doing. But, [Norm] will put you in straight decimal form. To escape out of the Mode screen after you select [Norm], just [2nd][Clear] to quit should take you to Home screen.

I have a student who just got a new calculator (TI-84). when you press the exponent button (x2) or the carrot button the numbers following the exponent stay superscripted. How do I adjust it so she can...

There's nothing wrong, the calculator just has the newest version of the operating system. To tell the calculator you're finished entering the exponent, simply press the right-arrow. If you don't want the new MathPrint mode, press MODE, press up-arrow to get to the second page, keep pressing up-arrow to get to the top line, highlight CLASSIC, press ENTER, then press 2ND [QUIT]. Now the calculator will display as the older operating system did.

The new MathPrint mode shows exponents, roots, fractions, and other things more like they appear in textbooks.

To do fractions, input like this:
Granted the answer is a decimal... But you should be able to convert that to a fraction using what you've learned in math class.

PI sign: Just press [2nd]and then[^]. And voila, instant π! Exponent:enter more complicated expressions involving exponents using parentheses and the negative sign.
