Answer 2

Answer:

a.) 11x³y⁴

b.) 7xy

c.) 9x

d.) 64x5x5

Step-by-step explanation:

A.) 4xy + 2x²y + 3y² + 5x²y²

= 4xy + 2x² × y + 5x² × y²

= 4xy + 2x² + 5x² × y × y²

= 4xy + 7x² × y³

= 4xy + 7x²y³

= 4 x × y + 7 x × x × y × y × y

= 4 + 7 x × y × x × x × y × y × y

= 11x³y⁴

b.) 4xy + 3

= 4 × x × y + 3

= 4 + 3 × x × y

= 7xy

c.) 7x + 2

= 7 × x + 2

= 7 + 2 × x

= 9×x

= 9x

d.) 32 + 22xy + 3x² + 7y² + x²y²

= 32 + 22× x × y + 3 × x × x + 7× y × y + x × x × y × y

= 32 + 22 + 3 + 7 × x × y × x × x × y × y + x × x × y × y

= 64x³y³ + x²y²

= 64x5y5 (after x and y there is 5 so , this five is of power)

= 64x5x5
