Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx, and logy.logy4x5Answer:
Identify Properties: Identify the properties used to expand log(y4x5). We will use the quotient property of logarithms to separate the numerator and denominator, and the power property to bring down the exponents. Quotient Property: logb(QP)=logb(P)−logb(Q) Power Property: logb(Pk)=k⋅logb(P)
Apply Quotient Property: Apply the quotient property to the logarithm.Using the quotient property, we can write log(y4x5) as log(x5)−log(y4).
Apply Power Property: Apply the power property to both terms.Using the power property, we can bring down the exponents in both terms:log(x5) becomes 5×log(x), and log(y4) becomes 4×log(y).
Write Final Form: Write the final expanded form.The final expanded form of the logarithm is 5⋅log(x)−4⋅log(y).
