(b) 23×[19-12]=(23×19)-(23×12)




please give me ans​

Answer 1

Answer:

a)Here we observe that LHS=RHS;

-180=-180 Hence associative property holds true b)Here also we observed that LHS=RHS;

161=161 Hence associative property holds true.

Step-by-step explanation:

a)LHS = 15×-12= -180

RHS= -105+285=-180

b)LHS=23×7=161

RHS=437+(-276)=161

In both cases LHS =RHS

Hence, proved.
