Q. Consider the numbers 4n, where n is a natural number. Check whether there is any value of n for which 4n ends with the digit zero.
Understand the Problem: Understand the problem.We need to determine if there is a natural number n such that when multiplied by 4, the product ends with the digit 0.
Analyze Number Properties: Analyze the properties of numbers ending with zero.A number ends with the digit zero if it is a multiple of 10. This means that the number must have 2 and 5 as factors.
Prime Factorization of 4: Consider the prime factorization of 4.The number 4 is 22 in prime factorization. It has the factor 2 but lacks the factor 5.
Introducing Factor 5: Determine if multiplying 4 by a natural number n can introduce the factor 5.Since 4 does not contain the factor 5, multiplying it by any natural number n will not introduce the factor 5 unless n itself contains the factor 5.
Check for Multiple of 5: Check if n can be a multiple of 5. If n is a multiple of 5, then 4n will have both factors 2 and 5, which are required for the product to end with zero.
Concluding Solution: Conclude if there is a value of n that satisfies the condition.Yes, if n is any natural number that is a multiple of 5, then 4n will end with the digit zero.
