✔ 最佳答案
log a × 2 b = log a + log 2 blog a b = log a +log b
log a × 2 b - log a b
= (log a + log 2 b) – (log a +log b)
= log b
log b ÷ log a b
= log b ÷ (log a + log b)
= log b / log a + log b / log b
= log b / log a + 1

log 2b - log b = log b ?!

(log a^2 b-log ab)/(log a)b
=log [(a^2 b)/(ab)]/(log a)b
=log a/(log a)b
=1/b
=log [(a^2 b)/(ab)]/(log a)b
=log a/(log a)b
=1/b
