Question

prove that 2-5✓3 is irrational
​

Answer 1

Answer:

suppose 2-5root 3is rational

let 2-5root 3 =p/q(where p, q are co-primes)

5 root 3=p/q-2

5 root 3=p-2/q

root 3=p-2q/q

I.e irrational number= rational number

which is a contradiction.

therefore, our assumption is false.

hence, 2-5 root3 is irrational.
