A disjunction is false if both parts of the disjunction are false; otherwise, it is true
----------------------------------------------
Choice A
4-3=2 is false
6*3=9 is false
both parts are false, so overall the entire disjunction is false
----------------------------------------------
Choice B
5*6=30 is true
3+4=7 is true
Neither part is false, so overall the entire thing is true
----------------------------------------------
Choice C
8+3=11 is true
5*4=23 is false
While second piece is false, the overall disjunction is true. The first part (true) makes the whole thing true.
----------------------------------------------
Choice D
7+6=13 is true
5*2=10 is true
Neither part is false, so overall the entire thing is true
----------------------------------------------
----------------------------------------------
In summary, we have
A. False
B. True
C. True
D. True
Making choice A the only answer that is false. So choice A is the final answer
Answer:
use the antilog formula to get the answer
Solving the expression 
we get value of x: 
or 
Step-by-step explanation:
We need to solve the equation and find value of x
Solving:
Adding 5/3 on both sides
Simplifying:
Multiply 6/5 on both sides:
So, solving the expression we get value of x: or
