Question

Check whether 8n end with the
digit zero for any
natural
number n​

Answer 1

Answer:

In case of terms like , the value x must contain zero or zeroes at the end otherwise it must have the factor as 5 or 10. It doesn't have 5 to make the two as 10. Therefore, for cannot end with the digit zero for n having any natural number.

Step-by-step explanation:

Given:

A number 8n

We need to check whether it can end with zero

Solution:

We know that any number is multiplied by 5 or 10 or by the multiples of 10 ends with zero.

So here the number 8 has factors 1,2,4 and 8.

It does not contain 5 and 10 as prime factors

8n = (2 X 4)n doesn’t have 5 in its prime factorization

Hence, 8n cannot end with the digit 0
