Question

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

Answer 1

nooo.

if 6n is to end with 0 for natural no. n

it should be divisible by 2 or 5

this means that the prime factorization of 6b should contain 2 And 5

but it is not possible

6n= (2×3)n= 2n × 3n

since 5 is not there in prime factorization there is no natural no. n for which 6n ends with the digit 0
