Solve for t using natural logarithms

5e^5t=7e^4t

I tried doing it 3 or 4 times, but I don't seem to be making much progress. The answer is rounded to 3 places.

Take logs of both sides:



Now use the properties of logs to finish up.

Properties of logarithms, refresh me on those? The highest math I took in HS was trig and I don't think there's anything like this problem in my notes. If you don't have the time, no big deal I'm sure I'll figure it out. Thanks for the help.

since for all ...







you still need to learn the properties of logs ... you'll need them.
