Evaluate log base 6 of -36
Problem
Solution
Identify the definition of a logarithm. The expression
(log_b)(x)=y is equivalent to the exponential formb^y=x Set up the equation for the given problem. We are looking for a value
y such that6^y=−36 Analyze the domain of the logarithm function. The argument of a logarithm,
x must be a positive real number (x>0 because a positive base raised to any real power always results in a positive value.Determine the existence of a real solution. Since
6^y is always greater than0 for all real values ofy it can never equal−36 Conclude that the expression is undefined in the set of real numbers.
