Which of the statements below is incorrect?
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:B
Which of the statements below is incorrect?
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
Explanation: a) Because loga a = 1, log10 10 equals 1.(b) log (2 + 3) = log 5 and log (2 x 3) = log 6 = log 2 + log 3 ,log(2 + 3) log(2 + 3) log(2 + 3) log (2 x 3),(c) Log10 1 = 0 since loga 1 = 0.(d) log (1 + 2 + 3) = log 6 = log (1 x 2 x 3) = log 1 + log 2 + log 3.
