Find the Domain natural log of 15=x
Problem
Solution
Identify the nature of the task. The expression
ln(15)=x is a logarithmic equation wherex is the value of the natural logarithm of a constant.Determine the domain of the natural logarithm function
ln(u) The domain of any logarithmic function is the set of all values for which the argumentu is strictly greater than zero (u>0 .Evaluate the argument in the given equation. The argument is
15 Check the condition for the domain. Since
15>0 the expressionln(15) is defined and represents a single real number.Conclude the domain of the variable
x in this specific equation. Becausex is set equal to a constant value,x is a single point. However, if the task refers to the domain of the functionƒ(x)=ln(x) evaluated at15 the domain of the natural log function is all positive real numbers.
