Using the Windows calculator in scientific view, we get:
17^23 = 19,967,568,900,859,523,802,559,065,713
which is 29 digits long, ie much longer than the capacity of most calculators.
Because both 17 and 23 are prime numbers, it isn't possible to simplify this calculation, so you will need to use find a calculator that has sufficient capacity to be able to handle numbers of this length.
The xnumbers add-in for Microsoft Excel can also be useful for this sort of calculation (do an internet search for it).
Using the Windows calculator, MOD55 of the above number is 18.
