Question

show that 14th cannot end with digit zero for any natural no.

Answer 1

Thanks for asking the question.

For the number to end with digit zero, its prime factorization should have 2 or 5 as a common factor.

Here 14^n=(2x7)^n does not have 5 in its prime factorization, therefore, 14^n cannot end with digit zero.

Hope it helps.
