Today is Thursday. What day is the 15th power of 365?

It's Friday
365^15
=365*365*365*…… *365 (15 365)
=(364+1)^15
=(364+1)^14*364+(364+1)^14
(364 + 1) ^ 14 * 364 is divisible by 7, because 364 is divisible by 7,
So (364 + 1) ^ 14 is left
The same repeated operation, the last is the remainder of 1
So Friday
