Hi, from the question given that let p and q be the two proportion, the four fission and using the law of proportional logics to show that p tends to q intersection q is equal to p intersection q.
00:32
So, first use the conditional identity, conditional identity.
00:45
So, here the left hand side lhs is equivalent to negotiation of p union q intersection p, since by using the conditional identity and now using the distributive law, distributive law.
01:13
So, this is equivalent to negotiation p intersection p union q intersection p.
01:24
Now, by using the component law, sorry complement law, by using the complement law, this is equivalent to this is false union q intersection.
01:46
So, again by the identity law, identity law, identity law says that p union false will be equivalent to p...
