Prove that 8- root 2 is irrational |
|
Answer» <P>Answer: Step-by-step EXPLANATION: √2 is an irrational number Suppose it can be WRITTEN in the form of p/q, and q is not equal to zero. When p and q are RELATIVE prime numbers √2= p/q~~eq(1) Where p and q are relative prime number TAKING square on both sides of eq(1) 2=p2/q2 Splitting q2 in two terms 2=p2/q.q Now, taking one q on other side 2q=p2/q~~eq(2) Since p and q being relative prime number, q cannot divide p and p2. As l.h.s of eq(2) is an integer i.e; na Hence, l.h.s of eq(2) is not equal to r.h.s. Hence, out assumption is wrong. So, it is proved that √2 is an irrational number. |
