See a solution process below:

To evaluate the expression in the problem, substitute:

$color(red)(4)$ for each occurrence of $color(red)(a)$

$color(blue)(3)$ for each occurrence of $color(blue)(b)$

$(color(red)(a)color(blue)(b))^2$ becomes:

$(color(red)(4) * color(blue)(3))^2 => (12)^2 => 144$

Or a dozen dozen.

Or a gross.
