    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.
