Question 45
LogarithmsIf loga3 = m and loga5 = p, find loga 75.
- A.m + p2
- B.2m + p
- C.m + 2p
- D.m2 + p
Show the answer and explanation
Answer: C (m + 2p)
Explanation
75 = 3 × 5², so loga75 = loga3 + 2 loga5 = m + 2p.
If loga3 = m and loga5 = p, find loga 75.
Answer: C (m + 2p)
75 = 3 × 5², so loga75 = loga3 + 2 loga5 = m + 2p.
