See a solution process below:

First, rewrite the expression as:

#3x^(3 xx 1/8)#

Next, use this rule of exponents to rewrite the expression again as:

#x^(color(red)(a) xx color(blue)(b)) = (x^color(red)(a))^color(blue)(b)#

#3x^(color(red)(3) xx color(blue)(1/8)) => 3(x^color(red)(3))^color(blue)(1/8)#

Now, use this rule of exponents to write the expression as a radical:

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

#3(x^3)^(1/color(red)(8)) = 3root(color(red)(8))(x^3)#
