If log	a/b	+	log	b/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
Explanation:   log	a/b	+ log	b/a= log (a + b)   =&gt;log (a + b) = log a/b	x	b/a = log 1.   So, a + b = 1.   a + b = 1NSWER IS a + b = 1
<result>A</result>
If log	a/b	+	log	b/a= log (a + b), then:
