Question

Chand number 6 n n being a natural number end with the digit 5 give reason​

Answer 1

Let 6n ends with digit 0

Any number ending with digit 0is divisible by 5

It means 6n is also divisible by 5

5 is a factor of 6then

But the prime factorization of 6is 2*3which do not have 5

Means 5is not a factor of 6

So 6n don't end with digit 0
