Question

prove that root 3+2 is irrational ​

Answer 1

Answer:

A rational number can be written in the form of p/q. p,q are integers then (p-2q)/q is a rational number. But this contradicts the fact that √3 is an irrational number. ... Therefore,2+√3 is an irrational number.

Answer 2

Answer:

Step-by-step explanation:

Let 2+√3 is a rational number.

A rational number can be written in the form of p/q.

2+√3=p/q

√3=p/q-2

√3=(p-2q)/q

p,q are integers then (p-2q)/q is a rational number.

But this contradicts the fact that √3 is an irrational number.

So,our supposition is false.

Therefore,2+√3 is an irrational number.

Hence proved.
