(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] What's the formula for calculating large exponents?

Hi! I came across the following sum and was wondering if there was some kind of formula for solving it:

16^198

Is it some kind of binomial expansion? Do you calculate the last digits first, advancing to the previous ones later?

I can't use a calculator.

Please, please help. Sums like this might come in an assessment exam I'm sitting. Thank you very much!
