# 1
Start with the given equation.
Rewrite as
Note: for all any x where
Pull down the exponent using the identity
Multiply
So the solution is
# 2
Start with the given equation.
Convert to exponential notation.
Pull down the exponent using the identity
Evaluate the log base "e" of "e" to get 1
Multiply
So the solution is

Comment: log mean "exponent" or "power".
-----------------
1) x = log(base 5) 1
Comment: Your problem says "x is the exponent of 5 that gives you 1"
5^x = 1
x= 0____
===============================
2) x = log(base e)sqrt of e
Comment: Your problem says "x is the exponent of e that gives you (e)^(1/2).
e^x = e^(1/2)
x= (1/2)_____
============================
Cheers,
