In computer science, boolean representations are used to express logical operations and are a fundamental concept in programming and electronics. Boolean representations are used to simplify complex logical expressions and make them easier to understand and work with. In this article, we will explore the concept of boolean representations and examine which of the given options is a correct boolean representation.

What is a Boolean Representation?

A boolean representation is a way of expressing a logical operation using a combination of variables, operators, and parentheses. Boolean representations are used to simplify complex logical expressions and make them easier to understand and work with. They are commonly used in programming languages, electronics, and digital logic design.

Types of Boolean Representations

There are two main types of boolean representations: AND and OR. The AND operator is represented by a dot (.) or a multiplication symbol (*), while the OR operator is represented by a plus sign (+) or a vertical bar (|).

Understanding the Given Options

Let's examine the given options and determine which one is a correct boolean representation.

Option 1: xy'z

This option represents a boolean expression using the AND operator. The expression xy'z can be read as "x AND y' AND z". This is a valid boolean representation, but we need to determine if it is correct.

Option 2: xyz'

This option represents a boolean expression using the AND operator. The expression xyz' can be read as "x AND y AND z'". This is also a valid boolean representation, but we need to determine if it is correct.

Option 3: xy'z'

This option represents a boolean expression using the AND operator. The expression xy'z' can be read as "x AND y' AND z'". This is a valid boolean representation, but we need to determine if it is correct.

Option 4: 100 xyz

This option represents a boolean expression using the AND operator. The expression 100 xyz can be read as "1 AND 0 AND x AND y AND z". This is not a valid boolean representation, as the numbers 1 and 0 are not boolean variables.

Option 5: 100 xyz'

This option represents a boolean expression using the AND operator. The expression 100 xyz' can be read as "1 AND 0 AND x AND y AND z'". This is not a valid boolean representation, as the numbers 1 and 0 are not boolean variables.

Option 6: 100 xy'z'

This option represents a boolean expression using the AND operator. The expression 100 xy'z' can be read as "1 AND 0 AND x AND y' AND z'". This is not a valid boolean representation, as the numbers 1 and 0 are not boolean variables.

Determining the Correct Boolean Representation

Based on the analysis above, we can determine that the correct boolean representation is xy'z. This is because it is a valid boolean expression using the AND operator, and it does not contain any invalid characters or syntax.

Conclusion

In conclusion, boolean representations are a fundamental concept in computer science and are used to express logical operations. By understanding the different types of boolean representations and analyzing the given options, we can determine that the correct boolean representation is xy'z. This is a valid boolean expression using the AND operator, and it does not contain any invalid characters or syntax.
