solve logx - 1/2log(x+4) = 1

Question

anonymous · Answer

rewrite as log(x/sqrt(x+4))=1

anonymous · Answer

then solve 















x/(sqrt(x + 4) = 10

anonymous · Answer

oops latex is not working sorry

anonymous · Answer

go to x = 10 * sqrt(x + 4)
i assume the  base of the log is ten

anonymous · Answer

Yeah, it is. But how did 1 go to ten, and how did you get rid of the log?

anonymous · Answer

because of the log base ten of x is y, then y is equal to ten to the power of x
they mean the same thing

anonymous · Answer

log (x) = y means 10^y = x
you should be able to switch back and forth quickly

anonymous · Answer

especially if you hate precalc.
it will not make it better, just easier to cope with

anonymous · Answer

Logarithms just throw me for a loop. I think I understand that.  Where would I go from x = 10 * sqrt(x + 4) ?

anonymous · Answer

I feel dumb, but at least I get it now.
