Hello,
To obtain the cube of a number you use the combination [2nd][X^3] that is X raised to exponent three.
1[2nd][X^3] [=] gives 1
2 [2nd][X^3][=] gives 8
3[2nd][X^3][=] gives 27.
By changing the number you enter before pressing the key combination you generate the cubes of the whole number.
Hope it helps.

How do i do radicals expressions on a TI 30XA


On your calculator, in the 4th column and third row down you should see the root x symbol. In order to do a radical, just press a number and then press the root x and you shall get the square root of your number. Now in order to do this for cubed root, fourth root, etc, you have to hit the number you want to put in the radical, the 2nd key, look for the y^x key in the last column second row, and then the number outside the radical. For example, if you wanted to do the cubed root of 8, you would hit 8, 2nd y^x, 3, and you should get 2.
