Question

Prove that 2-√3 is irrational

Answer 1

Answer:

let us suppose that 2-√3 is irrational number and it can express it in the form of a/b where a and b are co prime no.

2-√3=a/b

√3=a/b-2

√3=a-2b/b

we know that √3 is irrational no. so our assumption is wrong. so, 2-√3 is also an irrational no...
