Answer :
Answer :
(4) None of the above
Explanation :
For the equation log5x + log3x to be true, both logarithms need to have the same value. This is because adding logarithms with the same base is equivalent to multiplying the arguments (the values inside the logarithm).
However, logarithms with different bases (like 5 and 3 in this case) cannot be directly added or equated. They represent the exponent needed to reach a certain value under different bases. So none of the options are correct.
