The expression ( mn ) when ( m = 8 ) and ( n = 3 ) is
In algebraic expressions, variables such as ( m ) and ( n ) represent unknown or changing quantities. In this case, ( m ) is given as 8, and ( n ) is given as 3. To evaluate the expression ( mn ), substitute the values of ( m ) and ( n ) into the expression and perform the multiplication. Thus,
Understanding the concept of substitution is fundamental in algebra. Substituting specific values for variables allows us to compute the numerical result of an expression. In this instance, substituting the given values into the expression ( mn ) yields the final result of 24.
This skill is crucial in various mathematical and real-world applications, enabling the calculation of specific outcomes based on known values of variables. Additionally, it serves as a foundational step in solving equations and expressing relationships between different quantities.
