Evaluate 3 to the power of 3 + 6 (2 + 3/6)

If 3 + 6(2 + 3/6) is actually the power, then simplify 3 + 6(2 + 3/6) as a first step.  Must follow Order of Operations rules (PEMDAS):  mult and div BEFORE addition and subtraction. 

Thus, 3 + 6(2 + 3/6)  = 3 + 6 (15/6)
                                   = 3 + 15  =  18.

Then:  3^18 is the answer.  You could expand this if you wanted, but what would be the point of that?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
