Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx,logy, and logz.logzx23yAnswer:
Identify Properties: Identify the properties of logarithms that will be used to expand the given logarithm.The properties of logarithms that we will use are the quotient property, the power property, and the property for the logarithm of a root.
Apply Quotient Property: Apply the quotient property to the given logarithm.The quotient property states that logb(QP)=logb(P)−logb(Q). Therefore, we can write log(zx23y) as log(x23y)−log(z).
Apply Power Property: Apply the power property to the term log(x23y). The power property states that logb(Pk)=klogb(P). We can apply this to the term x2 to get 2log(x)+log(3y).
Apply Root Property: Apply the property for the logarithm of a root to the term log(3y). The property for the logarithm of a root states that logb(kP)=k1logb(P). We can apply this to the term 3y to get 31log(y).
Combine Results: Combine the results from the previous steps to get the final expanded form.We have 2log(x)+31log(y)−log(z) as the expanded form of the given logarithm.
