Question

The difference between the logarithms of sum of the squares of two positive numbers A and B an
the sum of logarithms of the individual numbers is a constant C. If A = B, then C is
(a) 2
(b) 1.3031
(c) log2
(d) exp(2)​

Answer 1

Answer:

The difference of the logs is the log of the quotient. The log of a difference cannot be simplified. An exponent on the log is NOT the coefficient of the log. Only when the argument is raised to a power can the exponent be turned into the coefficient.
