    The given problem is (7x) 3 x (3y) 2

    Let us analyse the problem in steps. The formula to be used is

    (ab) n = a n x b n

    where, a and b can be either constants (numbers) or variables (like x, y, z.....)

    Let us verify this with an example.

    Let a = 1, b = 2 and c = 3

    (ab) n = (1 x 2) 3 = 2 3 = 2 x 2 x ...

    This shows how to simplify an equation with variables and powers.
