See a solution process below:

Explanation:

First, we can rewrite the radical using this rule:

#root(color(red)(n))(x) = x^(1/color(red)(n))#

#(root(color(red)(3))(7p))^2 => ((7p)^(1/color(red)(3)))^2#

Now, we can use this rule of exponents to combine the inner and outer exponents:

#((7p)^color(red)(1/3))^color(blue)(2) => (7p)^(color(red)(1/3) xx color(blue)(2)) => (7p)^(2/3)#
