Hi, I am having a hard time solving for t using logarithms.

Equation is :

40000 + 2000t = 38500 (1.05)^t

Any help would be appreciated.

Thanks!

To solve this algebraically, you have to use the Lambert W function

Lambert W function - Wikipedia, the free encyclopedia

Here are some other examples where the Lambert W function is needed.

Try searching Math Forum for other threads where the Lambert W function is needed.

Hope this helps. Have fun exploring the world of math. - June 11th 2009, 08:09 PMpeterpater
