2^10/10 = 2^10/(2)(5) = 2^9/5 = = 512/5 --> R = 2

hey ..

if you look at the 2^x u will find the sequence..

2 - 4 - 8 -16 - 32- 64 - 128 - 256 - 512 - 1024 - 2048 - 5096 .....etc
if you look at the correlation ...

the last digit always follows the sequence 2 - 4 - 6- 8 .

therefore : 2^10/ @^1 / 5 = 2^9/5

the 9 digit of the sequence is : 2 . .. and we know that the it is < 5 and hence the reamider would be 2.

I know this is a long way to approah the problem but , felt this if you can remember the sequence it could come in handy in other problems..

Thanks..

Yeah , as per what u do it is 4 , but aint this also right 2^10/2.5 = 2^9/5 = 512/5 , thus reminder is 2 .

What is the answer then?

well to put in simple terms say what's the reminder when 4 is divided by 10 now will u say 4 or will u say 2 ..

i believe the answer will be 4 because the question is when 4 divided by 10 and not when 2 divided by 5 .

Hence i stand by my answer 2^10/10 will leave reminder 4 .
