Which of the following is not a boolean expression?True3 == 43 + 43 + 4 == 7

To determine which of the given expressions is not a boolean expression, we need to evaluate each expression and check if it results in a boolean value (either True or False).

Let's evaluate each expression one by one:

1. True This expression is a boolean expression because it directly represents the boolean value True. Therefore, it is not the answer we are looking for.

2. 3 == 43 This expression compares the value of 3 with 43 using the equality operator (==). The result of this expression is False because 3 is not equal to 43. Hence, this expression is a boolean expression.

3. 43 + 43 + 4 == 7 This expression adds the values 43, 43, and 4, and then compares the sum with 7 using the equality operator (==). The result of this expression is False because the sum of 43, 43, and 4 is not equal to 7. Therefore, this expression is also a boolean expression.

Based on the evaluation of each expression, we can conclude that all of the given expressions are boolean expressions. None of them is not a boolean expression.
