Thank you all for trying. Forget 6 digits. My exam's tomorrow afternoon, so if it'd be easier to find the last two digits without using a calculator, could you guys show me how? I'd just like to have an idea even if I can't answer.
I can do the approximations, but is there any way to find the last 6 digits? The question asked for both the approximation and the last 6 digits, so I thought perhaps the method would be similar and that there would be a formula.
Does this have something to do with modular mathematics...
[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...
