2x2y
8x2y
To find the product of (8x^2y) and (7xy^3z), multiply the coefficients and the variables separately. The coefficients give (8 \times 7 = 56). For the variables, combine them: (x^2 \times x = x^{2+1} = x^3), (y \times y^3 = y^{1+3} = y^4), and (z) remains as is. Thus, the final product is (56x^3y^4z).
