Question about Casio Office Equipment & Supplies
The trick with this type of question is to remain within the capacity of the calculator you are using. 3^97 gives an answer that is well over the capacity of most calculators so we need to break the calculation down into smaller chunks that remain within the calculator's capacity.
One way to do this is to calculate (3^20)mod353 and then multiply the answer by itself four times, which takes us to (3^80)mod353. Then calculate (3^17)mod353 and multiply it with the previous answer, taking us to the required (3^97)mod353 = 40. You can check this with the standard Windows scientific calculator.
The reason this works is that we are removing as many multiples of 353 as possible at each stage of the calculation, rather than removing all the 353's right at the end. It also requires us to know that power numbers can be added together.
