    logarithms

    Hi, im new in algebra, but got this question.
    solve
    log4 (x+4) -2log4 (x+1)=1/2

    From one of the first rules i see that

    log4 (x+4)/((x+1)^2)=1/2

    Then what do I do?;p

    There was a rule even before the one you mentioned. \displaystyle \log_a b = c \Longleftrightarrow a^c = b

    Can you finish up?
