Question

can the number 6 to the power n and, n being a natural number, end with digit 5? Give reason ​

Answer 1

Answer:

If a number ends with 5, then it is not divisible by 2. However, 6 is divisible by 2, and so every power of 6. That’s why no such power can end with 5.

Answer 2

1. if the number end with the digital zero then it is the factor of 2 and 5 but the factorization of 6power n is not end with the debit zero so the unique Ness of the fundamental mental theorem there is no any other prime factor of 6power n
