1. | Which of the following statements is not correct? |
A. | log10 10 = 1 | B. | log (2 + 3) = log (2 x 3) | C. | log10 1 = 0 | D. | log (1 + 2 + 3) = log 1 + log 2 + log 3
|

Answer: Option B
Explanation:
(a) Since loga a = 1, so log10 10 = 1.
(b) log (2 + 3) = log 5 and log (2 x 3) = log 6 = log 2 + log 3
log (2 + 3) = log (2 x 3)
(c) Since loga 1 = 0, so log10 1 = 0.
(d) log (1 + 2 + 3) = log 6 = log (1 x 2 x 3) = log 1 + log 2 + log 3.
