1.	Check whether 6n can end with the digit 0 for any natural number and
Answer» If any digit has the last digit 10 that means it divisible by 10.The factor of 10=2×5, So value of 6 n should be divisible by 2 and 5.Both 6 n is divisible by 2 but not divisible by 5.So, it can not end with 0. Yes, 6n can end with 0 . When we put n= 5 ( because n is any natural no.) Therefore 6*5= 30 which ends with 0. Thus, 6n can end with 0
