ln [5.01E3] = ln(4.86E2)  (1.80E2s1)(t s) Solve for t.
t = 126 s
First I did 4.86e2  1.80e2 and then on my calculator I pressed the 2nd button and then ln and got 1.031. Then I did the same thing to get the ln of 5.01e3 and divided that by 1.031 but did not get 126 as the answer. Where did I mess up?

Does the equation mean
ln(.00501) = ln(.0486)  (.0180s  1)(ts)?
Doesn't look like that's what you were doing. Try reposting with plenty of parentheses for clarity.
Use ^ for power if needed as in s^(1) for 1/s 
yes that's what it means and how I posted it is exactly how it is written on my homework but I just cant seem to get that answer.
