Which of the following statements is not correct?
log(2×4×6)= log 2 + log 4 + log 6
$log_{5}1=0$
log(3+4) = log(3 × 4)
$log_{5}5 = 1$
Explanation:
$Log_{b}b$ = 1. $Hence \:log_{5}5$ = 1
$Log_{b}1$ = 0. $Hence\: log_{5}1$ = 0
log(a × b) = log a + log b
similarly, log(a × b × c) = log a + log b + log c
Hence log(2×4×6) = log 2 + log 4 + log 6
log(3+4) = log(3 × 4) is wrong
LHS = log(3+4) = log 7
RHS = log(3 × 4) = log(12)
log 7 ≠ log 12
