can someone plzs help me
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)

algebra 
Reiny,
ln 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
