Back when I was writing the exam, I couldn't recall the formula correctly for this question: https://www.afterboards.in/past-year-questions/ipmat-indore/2021/SA/2
I just put all of it in a calculator and solved it in 2.5 minutes, ahah.
the exam calculator decieved me!!!! i got the correct answer from the scientific calc
Interesting, I used another calculator in a mock (of a different website) and it gave a whole new answer. I'd then recommend keeping an eye out for very big numbers (and verify them by multiplying the unit digits to confirm the final unit digit.)
That's one way to go about it. Not the ideal one though, let's say the numbers become even greater in coefficient and quantity, calculator won't support such big calculations then. Learn the other " not so smart way", just in case the calculator gives up on the d-day
okay!!
