Question

check whether 6n can end with the digit 0 for any natural number​

Answer 1

Let us take the example of a number which ends with zero so

10=2×5

100=2×2×5×5

Here we note that the number ending with

zero has both 2and5 as their prime factor

Whereas 6n=(2×3)

Does not have 5 as prime factor

so it does not end with zero

Therefore 6n cannot end with zero for any natural number n

Answer 2
