逻辑题:Determine whether each of this argument is valid .
Determine whether each of this argument is valid .If an argument is correct ,what rule of inference is being used If it is not ,what logical error occurs?
The number㏒23 is irrational if it is not the ratio of two integers .Therefore ,since ㏒23 cannot be written in the form a/b where a and b are integers ,it is irrational .

This argument is incorrect.The statement “log23 cannot be written in the form a/b where a and b are integers” occurs in the proof.No argument has been given to show that log23 cannot be written in the form a/b where a and b are integers.This is circular reasoning because this statement is equivalent to the statement being proved,namely,“The number log23 is irrational”.
