Question

check whether 6n can end with the digit 0 for any natural number end​

Answer 1

Answer:

The number whose last digit is 0 must be divisible by 2 or 5; hence in this question, check the given number whose power is to be calculated ends with 2 and 5 or not. Since 5 is not present in the factorial of 6 hence, we can 6ncannot end with 0.

Step-by-step explanation:

It can be observed that 5 is not in the prime factorisation of 6n. Hence, for any value of n, 6n will not be divisible by 5. Therefore, 6n cannot end with the digit 0 for any natural number n.

Answer 2

Step-by-step explanation:

The number whose last digit is 0 must be divisible by 2 or 5; hence in this question, check the given number whose power is to be calculated ends with 2 and 5 or not. Since 5 is not present in the factorial of 6 hence, we can 6ncannot end with 0.
