Let's first recall a couple of log identities: \[\left[\begin{matrix}\text{First} & x*\log(y) = \log(y^x) \\ \text{Second }& \log(x*y) = \log(x) + \log(y) \\\text{Third} & \log({x \over y}) = \log(x)  \log(y) \end{matrix}\right]\]From the First identity:\[\log(k^7) + \log(m^6)  \log(n^9)\]From the Second and Third Identity\[\log({k^7 m^6 \over n^9})\]

Same difference. I omitted the base for ease of typing it up. Remember these identities only apply when the base is the same.

What is the function? I'll type it in so you have an idea of how to type things in.
