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.

So I punched it in and the calculator reads:
P * A ^ 7
1613.078231
Did I do it correctly?
P * A ^ 7

Yes, I got the same answer.
The best way to check is to use numbers that you know, such as:
2^6=64,
2^20=1048576
3^4=81,
etc.
