Hint: We know that the value for log 1 to the base 10 is 0, but le us check what will be its value for base 3. For that, let be equal to x. Now, can be written as . Now, introduce log on both sides and use the property and simplify, we will get the value of x.
Complete step-by-step answer:
In this question, we have to find the value of log 1 to the base 3.
Now, we know that the value of log 1 to the base 10 is 0, but let us check what will be its value for base 3.
Let the log of 1 with base 3 be x. Hence, we can write it in equation form as
- - - - - - - - - - - (1)
Now, this is of the form , and we know the property of log that when a log of a number is given with base, we can write it as base raise to the value of log equal to the number. Hence,
If , then .
Using this property in equation (1), we get
Now, introduce log on both sides, ass we need to find the value of x
Now, we have another property of log that is . Therefore,
Now, the value of .Hence,
Hence, the value of log 1 to the base 3 is 0.
So, the correct answer is “0”.
Note: The value of log 1 to any base will always be equal to 0 only. Also, note that the value of log 0 to any base will always be equal to 1. Some of the important properties of logs are:
Product rule:
Division rule:
Power rule:
