Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....

Nope, there's a download online at TI's website but it's the same as the one that comes with the calculator.

Remove the six screws on the back cover. After the batteries are installed you need to reset the board. There is a little reset area that needs to be shorted to get the calculator back to normal. Look closely at the circuit board- You'll see a little circle next to the word reset. Its near the middle of the board. Wet your finger- press it on the circle. It should short. Blow it dry with your breath. It should work...

Two ways:

1) hit the equal sign

2) hit 2nd and [d/c] (you can do this multiple times to see it as the most reduced improper fraction or as a mixed fraction)

To find the cubed root (or any root) of a number, use the root() function.

If you want the cubed root of 125, you would type:

root(125,3)

### How do i find the exponential root using the TI-30Xa calculator?

Using logarithms. For example, if A ^ X = 2; then X = logA(2);
This calculator only works in base-10 logarithms or natural logarithms, you should use the base conversion formula.
logA(X) = logC(X) / logC(A).
Good luck!

### Variables

The TI-30XA cannot solve algebraic equations. You need a more advanced calculator for that, like the TI-89.
