Question

Check whether 6" can end with the digit 0 for any natural number​

Answer 1

Step by step explanation

Lets assume that 6n for any natural number n ends with the digit 0.If it has the common factor 5 .

Prime factors of 6 are

6 = 2 x 3

6 = ( 2 x 3 )n

Here 6 has the prime factors 2 and 3 which are the powers of n.

Since It does not have a common factor 5

Therefore 6 can never ends with the digit 0.

And our assumption was wrong.

Hope it helps.
