Question

Pls help Which of the following exponential equations is equivalent to the logarithmic equation below ? In x = 7

Answer 1

Explanation:

Let's write that out completely:

`ln_e(x)=7` The rule for going from log to exponential is what I call the "circular rule" in my classes and the kids never forget it. Take the base of the log, raise it to the power of the number on the other side of the equals sign, and then circle back to set it equal to the argument.

e is the base. Raise e to the 7th and circle back to set the whole thing equal to x (x is called the argument):

`e^7=x` choice C.
