Question

Which expression describes the area in square units of a rectangle has a width of 4x^3y^2 and a length of 3x^2y^3

Answer 1

Area is length x width:

4x^3y^2 x 3x^2y^3

Apply the exponent rule: a^b x a^c = a^(b+c)

4 x 3 = 12

x^3 x x^2 = x^5

y^2 x y^3 = y^5

Combine for final answer: 12x^5y^5
