Use \[\log a -\log b=\log \dfrac{a}{b}\]

Answer 2

umm how would i go about this?

Just compare the terms with the equation I gave above

lnx - ln5 =?

Answer 4

ln -x/5?

Answer 5

im kinda confused what to do with the 4

Answer 6

log x/5=4
This means

e^4=x/5

You can solve for x now!

Answer 7

ohh I understand now
so x=5e^4

Answer 8

AravindG, I thought it would become\[\ln(\frac{x}{5})=4\](not log, but ln, with base e)

Answer 9

Yes I was referring to natural log. You can see that I took e in the end though.So no worries :)
