Question

Can the number 6", n being a natural number, end with the digit 5? Give reason​

Answer 1

Answer:

Hope you understand my answer

Step-by-step explanation:

No it can not because as we know that the divisibility rule of 5 says that the number devided by five should end with 0 or 5 but the divisibility rule of 6^n says that the number devided by 6^n should be devided by 2^n and 3^n together.

edit: as 6^n do not satisfy the condition of 5 so it can not end with 5

Hope it helps you
