Solve without using tables log5(62.5) – log5((frac{1}{2}))

Solve without using tables log5(62.5) – log5((frac{1}{2}))
  • A.
    3
  • B.
    4
  • C.
    5
  • D.
    8
Correct Answer: Option A
Explanation

log5(62.5) – log5((frac{1}{2}))
= log5(frac{(62.5)}{frac{1}{2}}) – log5(2 x 62.5)
= log5(125)
= log553 – 3log55
= 3
