Check whether 6n can end with the digit 0 for any natural number |
|
Answer» If the no. 6 n for any n end with digit zero if the no. divisible by,5 .that is the prime factorisation contain 5 but this is not possible because 6n=(2×3)n.the prime factorisation of 6 n = 2 and 3 not 5 so there is no natural no. n for which 6 n end with digit zero 6n has 2 and 3 as it\'s factors. So it can\'t be written in the form of 2m5n. So it can\'t end with zero. |
