log 3 + log 6 - log 5 =?
- log(18/5)
- B. log(9/5)
- log(6)
- log(15/2)
Explanation
log 3 + log 6 - log 5
Step 1: Apply log addition rule
log a + log b = log (a × b)
So,
log 3 + log 6 = log (3 × 6) = log 18
Step 2: Apply log subtraction rule
log a - log b = log (a ÷ b)
So,
log 18 - log 5 = log (18 ÷ 5) = log (18/5)
