Question 199780
No you are correct. But there are many ways to enter that type of answer. 


You could enter the answer as {{{(4/3)z}}} or as *[Tex \LARGE \frac{4}{3}z] or *[Tex \LARGE \frac{4}{3}\ast z] (note: chances are that the computer wants to see the answer as *[Tex \LARGE \frac{4}{3}z], but that's just my guess). 


So this is why it helps to either see an example or ask the instructor the way the computer wants to see the answer.
