Lets assume that √7 is rational number. ie √7=p/q. we divide by the common factor to get √7 = a/b were a and b are co-prime number. that is a and b have no common factor.

Explanation:
Logarithm of 7
The number log 7 is an irrational number.
Definition of an Irrational Number
An irrational number is a number that cannot be expressed as a fraction of two integers and has a non-repeating, non-terminating decimal expansion. In other words, an irrational number cannot be written in the form p/q, where p and q are integers and q is not equal to 0.
Logarithm as an Irrational Number
The logarithm of a number is the exponent to which a base must be raised to produce that number. In the case of log 7, it represents the exponent to which a base (commonly 10 or e) must be raised to produce the number 7. Since 7 cannot be expressed as a fraction of two integers and has a non-repeating, non-terminating decimal expansion, the logarithm of 7 is an irrational number.
Conclusion
In summary, the number log 7 is classified as an irrational number due to its inability to be expressed as a fraction and its non-repeating, non-terminating decimal expansion.
