1. Given in prime factorized form then the number of divisors is . Use this to try to find the answer.
2. Since is prime it means . Thus, . Show this is not divisible by three by contradiction. If then . And thus, . Try to do the last one by substituting into the expression and seeing what you get.
3. We can write where . Thus, . Then, Use the above equation to reach the relationship you are trying to show.
