I compute (109/3)^1/4 and store that value in A.
Store 3 in P.
Now compute f(7)= Pa^7 by typing:
P x A x^y 7
***My problem is that I don't know WHERE the x^y key is on a TI -83 Plus.
Please help.
Then I have to subtract this answer from the answer using a rounded value of a (which I found to be 1831.)The difference will show the error used by rounding a and will not be zero.
