OpenStudy (abbycross167):

Like this @freckles ? (-.07xy^4)(.3x^3y) = -.07*.3 = -0.021 x*x^3= 2x^3 y^4*y= 2y^y4

OpenStudy (freckles):

first product is correct the last two products you found is incorrect where is the 2 coming from in front if you have 1 factor of x and then you put another 3 factors of x with it how many factors of x do you have?
