In this exercise we have to use the properties of the logarithm to write it in one way, like this:
[tex]log(r+s)(rs)^8/(rt)^3[/tex]
From these recalling some properties of the logarithm, we find that:
given the equation as:
[tex]log(s)log(r)+8log(rs)-3log(rt)\\log(s+r)+8log(rs)-3log(rt)\\logg(r+s)(rs)^8/(rt)^3[/tex]
