No. There are some keys on the TI-30XA that may make you think so, but they are statistical operations. For example, you can enter values using the Sigma+ key and the TI-30XA can give you the sum of the values entered, sum of the squares, mean value, standard deviation and so on.
You cannot do calculations like "Give me the sum of all integers from 1 to 100" with the TI-30XA, you'd need a far more sophisticated calculator.
The same way you would divide by any other number. Just use the EE key (just above the 7) to enter the exponent. If the exponent is negative, use the +<>- key (just to the left of the =) to enter the negative sign.
If you're asking about entering powers of ten, use the EE (enter exponent) key just above the 7. If you're asking about exponentiation, use the y^x key just above the divide.
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....
