Question

11. If 'n' is natural number then check 5n is a
number end with zero.​

Answer 1

Answer:

No, 5n cannot be end zero.

Step-by-step explanation:

Because if a number has to be end with a zero it should be divisible by both 2 and 5. But 5n is divisible by only 5 so it cannot end with a zero.

Answer 2

Answer:

if the number 5n,for any n were to end with the digit zero then it would be dividable by 2 and 5 that is the prime factorization of 5n would contain the prime 2 this is not possible because 5n so only primes in the factorization of 5n is 5 only . therefore there is no natural number n for which 5n ends with digit zero.
