143

You would substitute the given values in x and y ;

$4^{3} {(- 3)}^{2} + 4^{2} {(- 3)}^{3} - (4 - 3)$ $4^3(-3)^2+4^2(-3)^3-(4-3)$

$= 64 \cdot 9 + 16 (- 27) - 1 = 576 - 432 - 1 = 143$ $=64*9+16(-27)-1=576-432-1=143$

What is the value of the expression x^3y^2+x^2y^3-(x+y)x3y2+x2y3−(x+y)x^3y^2+x^2y^3-(x+y) when x=4 and y=-3?
