Question 54042
This is not possible for two reasons.
1. You can't take the log of 0.
2.  There's no power that you can raise anything to that will give you 0 and by the zero product property (0.78^t) has to equal 0 so that when it's multiplied by 150 you get 0.
Check the problem for type-o's just in case you typed it in wrong.
Happy Calculating!!!
