Question

Prove that irrational no 3by root 5

Answer 1

Answer:

Let it be rational number

therefore it can be written in form of a and b where a and b are co-prime numbers.

2√3=5a/b

5a/b is rational number as it is of the form p/q which is a rational number.

but we know that √3 is irrational number so our assumption is wrong.

2√3/5 is irrational.
