solve the equations by finding the exact solutions

ln(x)-ln(5)=7

the next one is

ln(e)=ln(with a v like symbol with 2/x)-ln(e)

**Reiny**, Sunday, October 28, 2012 at 5:26pmln x - ln 5 = 7

ln(x/5) = 7 , by rules of logs

x/5 = e^7 , by definition of ln

x = 5e^7

= appr 5483.2

I can't make out the second one
