Question

prove that any any number
$6 ^{2}$
cannot be end with unit 0​

Answer 1

Answer:

Yes , it cannot end with 0 .

Step-by-step explanation:

Reason: We know that a no. ending with 0 is a multiple of 10 and

prime factorisation of 10 gives 2×5 whereas prime factorisation of 6 give us 2×3

Hence 6 has prime factor 2 common with 10 but it doesn't have 5.

Hence the no. can't end with 0.

Hence proved
