First, the need to determine if the statements are true or false.
1) 6+3 =9 (This statement is true)2) 5*5=20 (This statement is false since 5*5=25)
With this in mind we can determine that what will illustrate the truth value would be:
T F -> F
In other words, since the first statement is true and the second statement is false then conjunction of both statements would be false.
