Final answer:
To evaluate the expression 13n when n=6, you multiply 13 by 6 to get 78.
Step-by-step explanation:
In algebra, evaluating expressions involves substituting specific values for variables. In the given expression,13n, the coefficient 13 indicates multiplication. When asked to evaluate it for n=6, you substitute 6 for n, giving 13×6.The order of operations dictates multiplication first, resulting in 78. This illustrates the fundamental concept that a coefficient next to a variable implies multiplication. The evaluation process demonstrates the application of algebraic rules, facilitating the transformation of symbolic expressions into numerical values based on given substitutions, in this case, yielding 78 for n=6.
