Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx,logy, and logz.logzy2x2Answer:
Apply Quotient Rule: Apply the quotient rule of logarithms to the expression log(y⋅y2x2). Quotient rule of logarithms: log(ba)=log(a)−log(b)log(y⋅y2x2)=log(x2)−log(y⋅y2)
Apply Product Rule: Apply the product rule of logarithms to the denominator part of the expression log(y⋅y2).Product rule of logarithms: log(a⋅b)=log(a)+log(b)log(y⋅y2)=log(y)+log(y2)
Apply Power Rule: Apply the power rule of logarithms to the expressions log(x2), log(y), and log(y2). Power rule of logarithms: log(an)=nlog(a) log(x2)=2log(x) log(y)=log(y21)=21log(y) log(y2)=2log(y)
Substitute Results: Substitute the results from Step 3 into the expression from Step 1.log(yy2x2)=2log(x)−(21log(y)+2log(y))
Distribute and Combine: Distribute the negative sign and combine the logarithmic terms involving log(y).2log(x)−(21)log(y)−2log(y)=2log(x)−(21+2)log(y)
Simplify Expression: Simplify the expression by combining the coefficients for log(y).2log(x)−(21+2)log(y)=2log(x)−(25)log(y)
Write Final Form: Write the final expanded form of the logarithm.The final expanded form is 2log(x)−(25)log(y).
