Check whether 6power n end with digit 6 |
|
Answer» If any NUMBER ends with the DIGIT 0, it should be divisible by 10 or in other words, it will also be divisible by 2 and 5 as 10 = 2 × 5 Prime factorisation of 6n = (2 ×3)n 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. |
