Question

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

Answer 1

If the number 6^n were to end with the digit 0, then it would have 5 and 2 as its prime factors, but we know that 6 has 2 and 3 as prime factors. So, there is no natural number n for which 6^n ends with a digit 0.

Answer 2

Answer: N is a natural no  

6n is divisible by 5

But the prime factor of 6 are 2 and 3

6n=(2*3)n

In the prime factor of 6n there is no factor of 5

There fore 6n dont end with 0
