If loga/b + logb/a = log (a + b), then:  Choose the correct option:
A) a + b = 1 B) a - b = 1 C) a = b D) a2 - b2 = 1 E) none of these
loga/b+ logb/a	= log (a + b)   log (a + b) = log((a/b)x(b/a))= log 1.   So, a + b = 1.   a + b = 1NSWER:a + b = 1
<result>A</result>
If loga/b + logb/a = log (a + b), then:
