An irrational number between 2 and 3 is: - Vidyadip

MCQ

An irrational number between $\sqrt{2}$ and $\sqrt{3}$ is:

A
$\big(\sqrt{2}+\sqrt{3}\big)$
B
$\big(\sqrt{2}\times\sqrt{3}\big)$
C
$5^{\frac{1}{4}}$
✓
$6^{\frac{1}{4}}$

✓

Answer

Correct option: D.

$6^{\frac{1}{4}}$

An irrational number between $a$ and $b$ is given by $\sqrt{\text{ab}}$
An irrational number between $\sqrt{2}$ and $\sqrt{3}$ is
$\sqrt{\sqrt{2}+\sqrt{3}}=\big(\sqrt{6}\big)^{\frac{1}{2}}$
$=6^{\frac{1}{2}\times\frac{1}{2}}$
$=6^{\frac{1}{4}}$
Hence, the correct answer is option $(d)$.
