Whether 8 power n, where n is a natural number, can end with zero?
Answer: No, 8 power n can't end with zero when n is a natural number.
Let's understand the solution in detail.
First, we have to write 8n in the form of prime numbers.
⇒ Hence, 8n = (2 × 2 2)n ---(1)
But we know that to end with zero, a number should be the multiple of 10, and hence, it should be the multiple of both 2 and 5.
But from equation (1), we can see that 8n can't have 5 as its factor.
