Question about Texas Instruments TI-81 Calculator

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 ^).

For an exponent of ten, use the EE (Enter Exponent) key located just above the 7 key.

Press the right-arrow key to tell the calculator you're done with the exponent. For your example, press

x ^ 3 right-arrow + 2

x ^ 3 right-arrow + 2

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.

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.

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:

(1/3)+(4/9)

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.

On the TI-36X there is no rooftop key, there is a yx key. This key is two keys below the on button. To use it, put the number in, press the yx key, put the exponent in, press the equal button.
