10xy(4xy^3-7xy+9y^2)

Thepotemich [5.8K]

Answer:

$40x^{2} y^{4} -70x^{2} y^{2} +90xy^{3}$

Step-by-step explanation:

$10xy(4xy^{3} -7xy+9y^2)$

1. 10xy · 4xy^3 = $40x^2y^4$

2. 10xy · -7xy = $-70x^{2} y^{2}$

3. 10xy · 9y^2 = $90xy^3$

Final step: add up all of those values together to make an equation!

Answer: $40x^2y^4+$ $-70x^2y^2+$ $90xy^3$

Final Answer: $40x^2y^4-70x^2y^2+90xy^3$
