Which of the following statements is not correct A ...........

Quantitative Aptitude (CDS) Logarithm

Which of the following statements is not correct?

A. log₁₀ 10 = 1

B. log (2 + 3) = log (2 x 3)

C. log₁₀1 = 0

D. log (1 + 2 + 3) = log 1 + log 2 + log 3

log₁₀ 10 = 1

log (2 + 3) = log (2 x 3)

log₁₀1 = 0

log (1 + 2 + 3) = log 1 + log 2 + log 3

(a) Since log_a 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)

(d) log (1 + 2 + 3) = log 6 = log (1 x 2 x 3) = log 1 + log 2 + log 3.

So, (b) option 2 is incorrect.
