Question

show that 9^n cannot end with digit o for any natural number n​

Answer 1

Answer:

Here is your answer...

Step-by-step explanation:

9n can never end with the digit 0 for any natural number n because for a number to end with zero it should be divisible by 10 and therefore its factors should be 5 and 2. But as 9 has only 3 as its factor, increasing its power will not make 5 as its factor. Thus it can never end with 0.
