Use logical cquivalences or a truth table to show that (pvq) r to (p r) a (q r)

The statement is logically equivalent to the statement

Step-by-step explanation:

We have the following statement and we need to prove that is logically equivalent to this statement .

To prove the logical equivalence of the statements we are going to use the table of logical equivalences as follows:

by the logical equivalence involving conditional statement.

by de Morgan’s laws.

by distributive laws.

by the logical equivalence involving conditional statement.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
