i guess its 72...but m sure this not the correct ans....coz we have 1000 as denom...so ans will b in decimal plz tell the correct ans[/quote]

Hi...i think ques is not very clear...it can be 402 raise to power 257/1000 or (402^257)/1000 but i think in both cases ans wud be 72....acc to me decimal shud not come in to picture cos we look for remainder....can anyone plz post d rite ans...

So
Out of given options only d=8 is a possibility where we can have some values for rest numbers
So d=8 can be a solution...rest all can't even be the solution. that's why i chose 8

let's take next highest number i.e. d=5 ..so d^2=25
a=1 nothing else possible...b=2 only value possible....no value for c is possible as for c=3 c^3>d^2.....so d=5 not possible..Since d=5 not possible..smaller number then that are definetely not possible

reminder for 88888888..by 45!

Ya i take on the preoblem is

888888888888......(888 times) by 45!
finding the number of zeros in the 45! that is
[45/5]+[45/25]= 10
so we can write 888888888888......(888 times) as
= 888888888888......(880 times) + 8888..(8times)

since the first term is divisible by 45! so we need to find the remainder of the second term by the 45! that comes out to be 888..8times

not pretty sure but i hope it is correct can any body else post its answer
