Thank you!

By the way, could one use the zero product property for the first exponential equation? - Sep 24th 2007, 08:50 AMjanvdl

Yes, I forgot the one at first, I'm sorry.

Yes I also thought about the zero product property,as

But I guess one could raise each term separately into the power. - Sep 24th 2007, 11:05 AMjanvdl
