Question 4
LogarithmsExpress in index form: logax + logay = 3.
- A.x + y = 3
- B.xy = 3
- C.x + y = a3
- D.xy = a3
Show the answer and explanation
Answer: D (xy = a3)
Explanation
logax + logay = loga(xy) = 3, so xy = a³.
Express in index form: logax + logay = 3.
Answer: D (xy = a3)
logax + logay = loga(xy) = 3, so xy = a³.
