okay so ive nearly finished this question and i dont understand the last few lines of the solution
-t = log(e) 1/4
-t = - log(e) 4
t= log(e) 4
okay so how did it get from 1/4 to 4 and why is there a minus sign in front of log in the second line ?
can you guys clear it up for me? thanks

-
log(1/4) = log(4^-1) = -1*log 4 = -log 4
