Question : The value of exponential form of $\sqrt{\sqrt{2}\sqrt{3}}$ is:
Option 1: $6$
Option 2: $6^{\frac{1}{2}}$
Option 3: $6^{-\frac{1}{2}}$
Option 4: $6^{\frac{1}{4}}$
Correct Answer: $6^{\frac{1}{4}}$
Solution : Given: $\sqrt{\sqrt{2}\sqrt{3}}$ Simplifying this expression, we have, = $\sqrt{\sqrt{6}}$ = $\left (6^{\frac{1}{2}} \right )^\frac{1}{2}$ = $6^{\frac{1}{4}}$ Hence, the correct answer is $6^{\frac{1}{4}}$.
