What would be the value of (log a)2 -(log b)2

Alog(a+b)log(ab)

B3

Clog(ab)log(a/b)

DNone of these

| | Important Formulas | Topic: | Asked In CapgeminiHireMee |

Explanation:

Question is in the form of a2 - b2 so the formulae is
(a+b)(a-b)=a2 - b2 where a=loga,b=logb
substitute in the formulae we get
(loga+logb)(loga-logb)
(log(ab))(log(a/b))
