Question: prove that 3 upon 2 root 5 is an irrational number?
Answer: Irrational number: If a number can not be defined as p/q where, p and q are integers and q≠0, then it is called an irrational number. We need to prove that 3/2√5 is irrational. ... So, it can written in the form of p/q where p and q are distinct integers. It means 5 is the factor p² ⇒ 5 is factor of p.
