Year 12s: what will be the first way you research your future options? >>

What do i do with this log ?

- ((ln0.25)^2)

how to simplify?

Ask a beaver.

Seriously though:

-(ln\frac{1}{4})^2=-(ln1-ln4)^2=-(ln4)^2

If that really is simplying...

Wolfram says it doesnt simplify http://www.wolframalpha.com/input/?i=-%28ln%280.25%29%5E2%29

however, if it was -ln(0.25^2) it would simplify to ln(16) which is 4ln(2)

edit: I say it doesnt simplify, it probably does, but I dont fully understand most of the options given, other peoples answers may be better.
