Question

W = 5x 3y 4 − 7y 4x 3 − 2x 5y 7 + 10x 3y 4 − 8x 5y 7 − 2y 7x 5

Answer 1

Respuesta:

-324xy

Explicación paso a paso:

5x 3y 4 − 7y 4x 3 − 2x 5y 7 + 10x 3y 4 − 8x 5y 7 − 2y 7x 5

5x.3y.4=60xy

7y.4x.3=84xy

10x.3y.4=120xy

8x.5y.7=280xy

(2x.5y.7)+(2y.7x.5)=140xy

=60xy-84xy-140xy+120xy-280xy  

=-324xy
