Question

Calcula x.y. si:
CA o complemento aritmetico (xy)+CA (xyxy) =3164

Answer 1

(100-xy)+(10000-xyxy)=3164

HACEMOS DESCOMPOSICION POLINOMICA*

(100-10x-y)+(10000-1000x-100y-10x-y)=3164

100-10y-y+10000-1000x-100y-10x*y=3164

10100-1020x-102y=3164

10100-3164=1020x-102

6936=1020x reemplazamos x por 6

6936-6120=102y

816=102y

8=y

A.B=6*8=48
