Homework Help: Algebra 2

Posted by HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!! on Wednesday, February 25, 2009 at 8:08pm.

how do not understand how to do this

Log X + Lob (X-3) = 1

I know I do this

Log X(X-3)=1

then I do this

Log X^(2) - 3X = 1

then I do this

2 Log (X-3X) = 1


2 Log (-2X) = 1


(2 Log (-2X) = 1)(1/2)

Log (-2X) = 1/2


(Log (-2X) = 1/2)(-1/2)

Log X = (-1/4)


by def

10^ (-1/4) = X

I get something under one and calculator tells me I can't do that I think I'm doing something wrong what do I do?
