Question

is 2/ √3a rational number? give reasons​

Answer 1

Answer:

2+√3 is an irrational number.

Step-by-step explanation:

To prove = 2√3 is an irrational number.

We shall prove this by the method of contradiction .

so let us assume to the contrary that 2√3 is a rational number =r

2√3=r

√3=r/2

Now we know that √3 is irrational number.

SO, r/2 has to be irrational to make the equation true .

This is a contradiction to our assumption . Thus our assumption is wrong .

Therefore,2√3 is irrational .
