Question

State whether the given statement is True or False :

$2\sqrt{3}-1$ is an irrational number.

• A. True
• B. False

Answer 1

The correct option is A True

$\text{Here 1 is a rational number and}$$2\sqrt{3}$ is a $irrational$ number

And $\text{the difference of rational and irrational is always an irrational number}$

So that $(2\sqrt{3}-1)$ is an irrational number.

hence option A is correct.
