Question

2 + root 3 is *
A) rational number
B) irrational number
C) negative number
D) perfect square number

Answer 1

Answer :

It's a Irrational number.

Let us assume that 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 assumption is false.

Therefore,2+√3 is an irrational number.

Hence proved.

Answer 2

Answer:

B

Step-by-step explanation:

Because 2+√3=3.732050807

which is not be writen in the form of p/q thus it is an irrational number.
