16 n can end with 0 for n belongs to N

Answer» It cannot end with digit zero because in 16 n (2×2×2×2) n is there and for ending with digit zero the number must contain 2 and 5 in its prime factors and 16 only contain 2 but not 5 that is why it cannot end with 0
16ⁿ = (2×2×2×2)ⁿPrime factorisation of 16ⁿ does not contain the prime factor 5. Therefore, 16ⁿ cannot end with digit 0 for any natural number n
