Lindsey Porter · Answer 1

You could also solve the answer using logarithmic rules.

log (a * b) = log (a) + log (b)

log (a / b) = log (a) - log (b)

Therefore

log (2) + log (3) - log (11)

log (6) - log (11)

log (6 / 11)

= - 0.263 to 3DP

Table of decimal logarithms, we have:

log 2 ≈ 0.30

log 3 ≈ 0.47

log 11 ≈ 1.04

Therefore:

Log (2) + log (3) - log (11) =

0.30 + 0.47 - 1.04 =

0.77 - 1.04 = - 0.27

Answer:

- 0.27
