Solving Compound Interest Problems PLEASE READ DESCRIPTION:)

I go over examples involving compound growth and continuous compound growth. Some examples require the use of logarithms to solve for an unknown time period. I apologize that this video has some inconsistent rounding errors.
The answer to the first equation without round off error is $40387.39

Here are my other PreCalculus lessons involving Logarithms

It is not a difference of your way or my way, you are seeing the power of round off error! If the entire expression is typed in a computer at once you get your answer. If you work out the problem in steps as I did, even going out quite a larger number of decimals, you will have some round off error. The high the powers, the more careful you need to be about rounding:) Thanks for watching and the comment!!!

Thanks for watching and supporting by subscribing....what are you waiting for?...go start sharing...LOL :D

[profrobbob]

eh..emm...did not skim that far into the video...sorry. In the last example the variable is still in the exponent. You can solve the equation by applying the log of any base you like to both sides, common log base 10...Ln...log base 2 if you want, your final answer will be the same excluding round off error. I had just used the natural log on the previous question so I used it again. A time stamp in your question will ensure I answer your question correctly:) Thanks for watching.

I often question why I bought my textbook when I can just watch your videos, lol.
I honestly learn more from you than my from my real-life teacher.
