Answer:


3\,log (x-2)+2\,log(x+2) can be written as the single logarithm:


log((x-2)^3\,(x+2)^2)

Explanation:

Start by using in both terms of the expression the property of logarithm of a power that states:


log(a^b)=b\,*\,log(a)

so we recognize that the factor that multiplies each logarithmic expression, can be understood as the power of the argument of the function logarithm:


3\,log(x-2)=log((x-2)^3)\\and\\2\,log(x+2)=log((x+2)^2)

Then we use the property of logarithm of a product which states that:


log(a*b)=log(a)+log(b)

So now we recognize the expression:


log((x-2)^3)\,+\,log((x+2)^2)

as the logarithm of the product:


log((x-2)^3\,(x+2)^2)

which is finally a single logarithm as requested.
