Q. Assertion–Reason Type Question

Statement-1: \( \left(\sqrt[m]{\sqrt[n]{a}}\right)^{mn} = a \)

Statement-2: \( ((a^m)^n)^p = a^{mnp} \)

✏️ Solution

\( \sqrt[n]{a} = a^{1/n} \)

\( \sqrt[m]{\sqrt[n]{a}} = (a^{1/n})^{1/m} = a^{1/(mn)} \)

\( \left(a^{1/(mn)}\right)^{mn} = a \)

So Statement-1 is TRUE

Statement-2 is also TRUE (law of exponents)

Statement-2 correctly explains Statement-1

Correct Option: (a)

\( \boxed{\text{(a)}} \)
