Solving an equation with logarithms

Postby phiv » Fri Nov 05, 2010 1:23 am

Hello,
I am having trouble isolating W in the following equation, because it is outside and inside the logarithm:





I tried a number of things, but I always end up with a W as an exponent, and a W that is not an exponent, and I am unable to isolate W.

Any advice?

Thank you,

you can't solve for w explicitly. If you want a solution you will have to do it numerically.

Turns out you are correct. The professor solved using trial and error values for W (ie. numerically).
