11^27 = 13,109,994,191,499,930,367,061,460,371 which is 29 digits long.

You can get this result from the Windows calculator (scientific view) by entering 11 and then pressing x^y 27 = . Then use Mod 29 = to get the result, which is 8.

Unfortunately the Casio fx-991ms (as with most other calculators) doesn't have nearly enough digits to cope with this type of calculation. You therefore need to split the calculation down into more manageable chunks, as follows, which works on most calculators:

First calculate 11^3 = 1,331 and work out Mod 29, which is 1,331 - 45×29 = 26.
Then calculate 26^3 = 17,576 and work out Mod 29, which is 17,576 - 606×29 = 2.
Finally calculate 2^3 = 8. Since this is less than 29, it is also the final answer as confirmed above.

This method can be used with any power number that can be factorised into numbers that don't cause the available digits of the display to overflow. In this case 27 = 3×3×3 so each step involves cubing the previous answer.

How to calculate 17^23mod55 in casio scientific calculator fx-991MS?


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.

360 degrees divided by 29 spaces


What do you really want to do? 360/29 gives 12.4137931 degrees. Is it not 360 divided by 30? That looks more common, and the result is 12 degrees. That is what you get if you want to inscribe a regular 30-gon in a circle.
