Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx,logy, and logz.logxz43yAnswer:
Identify Properties: Identify the properties used to expand the logarithm.We will use the quotient property and the power property of logarithms to expand the given expression.Quotient Property: logb(QP)=logbP−logbQPower Property: logb(Pk)=k⋅logbP
Apply Quotient Property: Apply the quotient property to the given logarithm.Using the quotient property, we can separate the numerator and the denominator of the fraction inside the logarithm.log(xz43y)=log(z43y)−log(x)
Apply Power Property z4: Apply the power property to the term z4 in the numerator.The term z4 can be expanded using the power property.log(z43y)=4⋅log(z)+log(3y)
Apply Power Property 3y: Apply the power property to the term 3y in the numerator.The cube root of y is equivalent to y raised to the power of 31.log(3y)=log(y31)=31⋅log(y)
Combine Results: Combine the results from steps 3 and 4.Now we combine the logarithms of z4 and 3y into a single expression.log(z43y)=4⋅log(z)+31⋅log(y)
Final Expanded Form: Combine all the results to get the final expanded form.Now we combine the results from steps 2, 3, 4, and 5 to get the final expanded form of the original logarithm.log(xz43y)=4⋅log(z)+31⋅log(y)−log(x)
