    indices & logarithms

    lg (4^p - 4) - p lg 2 = lg 3

    I got to lg (4^p-4) - lg 2^p(3) - lg 3 = 0
    And an answer of 9.58, but when checking back, it seems wrong.
    Please help

    Thanks

    Re: indices & logarithms

    One of the laws of logs you need to use is
    log(A)-log(B)=log(\frac{A}{B})

    Similarly
    log(A)+log(B)=log(AB)
