Module 1. Mathematics

log 100/2 =

  • 1
  • log 98
  • log 200

Explanation

Here log 100 is evaluated first to give 2, then divided by 2, so the result is 2 / 2 = 1. The 2 is a divisor outside the logarithm, so it does not become log 50 or any single-log expression of 98 or 200.

questions like this should be clearly set because there is a difference between : log 100/2 and (log 100)/2

log 100/2 = log 100 - log 2 = 2 - 0.3010 = 1.699
and

log (log 100)/2 = 2/2 = 1
