All multiples of 6 end with 0,6,2,4,8

But it does not end with 5

So, 6n cannot end with 5

But it does not end with 5

So, 6n cannot end with 5

*I think you're asking for 6^n.*

*No, 6^n cannot end with five.*

*For - "A ^ n" ( where A is any integer ), to end with 5 ( or have 5 in unit place ).*

*"A" must be in the form of 2 ^ m X 5 ^ n .*

*However, here 6 = 2 X 3*

*ie. 6 cannot be written in the form of 2^m X 5^n.*

*So, 6 ^n cannot end with five.*

*And for, 6n.*

*This too can't end with five, as all multiples of 6 end only with 0, 2,4, 6,8.*
