    I'm sure it's fairly easy to do this, but my book didn't explain how to do it and then i got asked the question. SO can somebody please solve this for me and show me the steps on how to do it please.

    Here it is: "Write the following expression in the form log x where x is a number." and then some example questions would be a) log 5 + log 2 or b) log 6 - log 3 or c) 2 log 6 and d) -log 7

    The three main rules for logarithms you need to know are:
    Log(a) +log (b) = log (ab)
    Log (a) - log (b) = log (a/b)
    (And this works for any Base as long as they're the same)

    Log (a^n) =nlog (a)
