Q. Find the value of \( \left(\frac{169^{-3}}{196^{-8}}\right)^{\frac{1}{48}} \)

✏️ Solution

\( = \left(\frac{(13^2)^{-3}}{(14^2)^{-8}}\right)^{\frac{1}{48}} \)

\( = \left(\frac{13^{-6}}{14^{-16}}\right)^{\frac{1}{48}} \)

\( = \left(13^{-6} \times 14^{16}\right)^{\frac{1}{48}} \)

\( = 13^{-\frac{6}{48}} \times 14^{\frac{16}{48}} \)

\( = 13^{-\frac{1}{8}} \times 14^{\frac{1}{3}} \)

\( = \frac{14^{1/3}}{13^{1/8}} \)

Final Answer: \( \boxed{\dfrac{14^{1/3}}{13^{1/8}}} \)
