Simplify logarithms?! write as single expression? I have a test which I NEED to do well on, this isn't me avoiding my homework, I've spent the past two hours crying because I couldn't figure anything out. like logv3(9*25) and 3 logv5(8) where v is a downwards carrot and * is a mulitplication sign. Please explain! Anything helps!
others could be:
logv4(16/64)
logv2(3)+logv2(6)
log7(x/49)
logv4(4/x)
solving for x:
logv8(2x+5)=logv8(11)
I think you can give points for answers right? I'd give most of my points to a helpful answer.
