Q. \( \sqrt[5]{3125a^{10}b^5c^{10}} \)
(a) \( 5a^2bc^2 \)    (b) \( 25ab^2c \)    (c) \( 5a^3bc^3 \)    (d) \( 125a^2bc^2 \)

✏️ Solution

\( 3125 = 5^5 \)

\( = \sqrt[5]{5^5 \cdot a^{10} \cdot b^5 \cdot c^{10}} \)

\( = 5 \cdot a^{10/5} \cdot b^{5/5} \cdot c^{10/5} \)

\( = 5 \cdot a^2 \cdot b \cdot c^2 \)

\( = 5a^2bc^2 \)

Correct Option: (a) \( 5a^2bc^2 \)

\( \boxed{5a^2bc^2} \)
