Let 3+2√5 is a rational number =a/b,then 2√5=a/b-3=(a-3b)/b and √5=(a-3b)/2b. This shows √5 is a rational number.But √5 is an irrational number. So 3+2√5 is irrational ## Lessons (7)

I am really surprised to know that you did not like my teaching. You wanted me to explain compound interest problems. I solved as many as 5 problems. Never ever you mentioned you did not follow,when I asked you about your understanding. I tried to involve you in the congruence of triangles,but you hardly participated. At the end of the session I had to inform you about the payment. Normally it is discussed with parents. Since you told no one is available,I had to inform you. Prior to demo class I called you several times to know the topic for demo session,but you never picked. Can you explain why you told in the class you were following?
