    Help with Logarithms and Exponents

    What's the condensed form of the following logarithmic expression?

    (1/4)log(x^2) - 2log(y) + log(4)

    use the properties of logs ...

    \log{a} + \log{b} = \log\left(ab \right)

    \log{a} - \log{b} = \log\left(\frac{a}{b}\right)

    c\log{d} = \log\left(d^c \right)

    Oh I see. I forgot the 3rd logarithmetic property. Okay, thank you.
