Math Problem Statement

Evaluate the following logical expression: NOT ((5 > 3) OR (6 < 10)). Is this True or False?

Solution

Let's evaluate the logical expressions in the image.

Question 1:

Logical expression:
NOT((5>3) OR (6<10))\text{NOT} \left( (5 > 3) \text{ OR } (6 < 10) \right)

  1. Evaluate the inner expressions:

    • 5>35 > 3 is True.
    • 6<106 < 10 is True.
  2. OR operator:

    • True OR True\text{True} \text{ OR } \text{True} is True.
  3. Apply the NOT operator:

    • NOT True\text{NOT True} is False.

Thus, the statement evaluates to False, and the selected answer is correct.


Question 2:

Logical expression:
((2+2=5) OR (8>5)) AND NOT(10>5)\left( (2 + 2 = 5) \text{ OR } (8 > 5) \right) \text{ AND } \text{NOT} (10 > 5)

  1. Evaluate the inner expressions:

    • 2+2=52 + 2 = 5 is False.
    • 8>58 > 5 is True.
    • 10>510 > 5 is True.
  2. OR operator:

    • False OR True\text{False} \text{ OR } \text{True} is True.
  3. NOT operator on 10>510 > 5:

    • NOT True\text{NOT True} is False.
  4. AND operator:

    • True AND False\text{True} \text{ AND } \text{False} is False.

Thus, the statement evaluates to False, but the selected answer is True, which is incorrect.


Would you like more details or further clarifications? Here are 5 follow-up questions:

  1. What is the difference between the AND and OR logical operators?
  2. How does the NOT operator affect a logical expression?
  3. Can you combine more than two logical operators in one expression?
  4. Why does (2+2=5)(2 + 2 = 5) evaluate to False in logical operations?
  5. How can De Morgan’s laws be applied to simplify logical expressions?

Tip: Always evaluate inner expressions first when working with complex logical statements, then apply operators like AND, OR, and NOT.
