The statement is simple and asks the expression to be simplified. The equation uses the log system and is expressed in a fraction in the natural log. Using the basic laws of logarithm and fundamentals, the expression falls to [imath]1/3.[/imath]
A natural logarithm solves the expression quickly, negating each log and putting the power values outside the record, giving you the answer without any hassle. There are several references listed in the discussion of this question.
The inverse property of logarithm means the input gets back when it is listed inside the log-in exponents. The same value returns on solving the log because it is the primary property of the natural logarithm. The value in exponents gets an out before it is applied on the constant holding the exponent.
Several references also highlight this logarithm property and are in the essential rule book of the logarithm. The connection highlights the derivatives equations of the logarithms and their exponentials.
These references highlight the derivation of this rule which states that any constant with the exponent in the log, the exponent will go out before the log is applied to that constant.
