change the log expression to an equivalent expression involving an expression.
ln x = 4
I said it was e^4 = x
am I right??

It might help to consider the definition of a logarithm.
Definition
The log of a number to a given base is the index of the power to which the base must be raised in order to give the number.
Example
if log is to base 10
log10 (100) = 2
Number = 100
base = 10
power = 2
10² = 100
Therefore:-
ln x = 4
e^4 = x
x = 54.6 (to 1 dec. place)

log (sub)8 sixteen - log (sub)8 2 is unquestionably a branch project and may well be rewritten as; log (sub)8 (sixteen / 2) through fact they're the two sub 8. now the respond is a million on each and every occasion the backside (sub 8) and the log are an identical. log (sub)8 (8).

Yes. The rules for logarithms are
Log_b (a) = c
means b raised to the power of c yields a.
In other words, a=x, b=e, c=4.

the question was probably "involving an exponential"....
in which case, yes that is correct, if you add the restriction x>0

You are correct.
Ln is just log base e
