Best ResponseYou've already chosen the best response.0or distribute the 4e^(4x) to the (8x+4)?

Best ResponseYou've already chosen the best response.1If the question asks you to simplify, I'm guessing to expand the bottom and cancel out whatever you can would be your best bet

Best ResponseYou've already chosen the best response.1But if I had written the above answer in an exam, I believe it would be good enough to secure the full marks, it really depends on what your teacher wants and how far he/she wants you to simplify it

Best ResponseYou've already chosen the best response.0well the question is to find the equation of the line tangent to the graph of that function at point (3,f(3)) and i know i have to take the derivative first so thats what i was doing... but you're saying that answer is good enough to continue solving the rest of the problem?

Best ResponseYou've already chosen the best response.1yep, because now you have to substitute and thats usually just done on the calculator, so there isn't much point in simplifying more than necessary and wasting time
