If log a + log b = log (a + b), then b a = log (a + b).
A. a + b = 1
B. a - b = 1
C. a = b
D. a2 - b2 = 1
Answer:A
If log a + log b = log (a + b), then b a = log (a + b).
A. a + b = 1 B. a - b = 1 C. a = b D. a2 - b2 = 1
Explanation: log a/b +log ,log (a + b) = b/a,log (a + b) = log a/b x b/a = log a/b x b/a = log 1.As a result, a + b = 1.
