Question

Solve for f(e^2,8)

Answer 1

\(\large f(e^2, 8) = \ln e^2 + 8^3\)

Answer 2

Isn't this straightforward ?

Answer 3

depends on how you interpret it ....

Answer 4

hmm may be tricky idk

Answer 5

when i first saw it, i assumed it meant:\[\ln~(x+y^3)\]
but the program that is grading it says its:\[\ln(x)+y^3\]

Answer 6

oh yeah ambiguity is always there w/o explicit parenthesis

Answer 7

yeah ... it bites when you get marked off for someone elses ambiguity :/

Answer 8

lol true :) genereally i get inclined to not include stuff into ln when parenthesis is not there

for ex

2a + 3 \(\ne\) 2(a+3)

ln a + 3 \(\ne\) ln(a+3)

agreed ambiguity is there, but our brains seem to resolve it reasonably...

Answer 9

ln(a) + 3 seems to look ugly, eventhough it is clear hmm just my opinion
