Total Posts: 2 | I am having a hard time finding out how to get the cube root of a number. I am used to my ti83+ but I need the 89 for college. the book doesn't cover simple stuff like where this is located so maybe someone can help me out. I feel really stupid asking something so simple but i can't find it. |

For the cube root of a number, just raise it 1/3. Like so: 27^(1/3)
So and so forth. Have fun!

^ It rasies a number to a certain power.
So, to find 25 to the 4th power is
25^4
Easy. |

Total Posts: 2486 | you can also make a simple program that'd do this for you, in case you're lazy typing things in...like me. i had a program do do about anything we're studying in math class. hehe. though, i wrote my own programs to do that, this is good task for you to learn programming and your math. though, there are tons of readily made programs which you can download and use. check out ticalc.org's archive if you even need math programs.
