also are there any uses of these all in our daily life?

there are interesting problems and formulas like ,

for example?

rational numbers are used in banks..

@myininaya and @UnkleRhaukus may also want to share their knowledge here

what about 4^56 ?

find the unit digit of 4^{56} /

uhh...4

fr 4 its 4,6,4,6

oh sry itz 6!

right is it necessary to have 4 chances ?
I mean that in 3 we took : 3 , 9 , 7 and 1
in 4 we took 4

similarly for 7 we will take:
7 , 9 , 3, 1

right?

yeah!

So i have:
7^{256} unit number as : 1

yeah.....

7^226 unit digit is 9

226/4 = remainder = 2 that is we have 9

yeah...

hmn thanks any more concept you know?
