See a solution process below:

Explanation:

Use this rule for radicals to simplify the expression:

sqrt(color(red)(a)) * sqrt(color(blue)(b)) = sqrt(color(red)(a) * color(blue)(b))

sqrt(color(red)(3)) * sqrt(color(blue)(7)) * sqrt(color(green)(2)) => sqrt(color(red)(3) * color(blue)(7) * color(green)(2)) => sqrt(42)
