A.

ln(1/e)=-1

exponential form:

(e)^-1=1/e

B.
ln(u)=s
exponential form:
e^s=u

C.

log(a,b)=c
exponential form:
a^c=b



Let x=t and y=u
write each expression in terms of t and u


A.
ln(ex)
=ln(e)+ln(x)
=1+ln(x).........if x=t
=1+ln(t)

B.

ln(e^2x sqrt(y))
=ln(e^2)+ln(x )+ln(sqrt(y))
=2+ln(x )+ln(y^(1/2))
=2+ln(x )+(1/2)ln(y).......x=t and y=u
=2+ln(t )+(1/2)ln(u)

I know how to do this. This is for anyone, including yourself, wishing to practice math when there's nothing to do.
