So this time we have three questions to solve and for the first question is we are asked to use through tables to verify these equivalences.
00:26
So the first one is p and t is equivalent to p.
00:35
So let's solve this one first one first.
00:37
So this is b and this is t, so 011, actually let me write it in t or f terms, so f f, f, t, t, and it's always t here because we end by t.
01:06
And the result is f and t is f, f and t is f, f and t is f, t and t is f, t and t is t.
01:15
T and t is t as we can see here.
01:18
So this is the result.
01:19
As we can see here for p is f f ftt and the result is the result of p or p and t is f f t so therefore p and t is equivalent to p and and for the next question is we have p or f equivalent to p.
01:49
So so now we have p, f, and then p or f.
01:56
So 0.
02:01
F, f, c, t, f, f, f, f, f, f, f, f, f, f, f is f, t, t, and t, as you can see here, the values are the same.
02:19
Therefore, p or f is equivalent to p.
02:23
For the next question we have b and f is equivalent to...
02:33
So now, this is b, this is f, this is f and f.
02:42
So f f, d, f, f, f, f, f, f, f is f, f, f, as we can see here, p and f, this is f, and f, this is the value for p and f, and this is the values for so it's all the same, so therefore b and f is equivalent to f.
03:08
For the next question, it's p or t is equivalent to t.
03:17
This is p, this is t, b or t...
