Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx,logy, and logz.logz5yxAnswer:
Identify Properties: Identify the properties used to expand log(z5yx). We will use the quotient property and the power property of logarithms to expand the given expression. Quotient Property: logb(QP)=logbP−logbQ Power Property: logb(Pk)=k⋅logbP
Apply Quotient Property: Apply the quotient property to log(z5yx). Using the quotient property, we can separate the logarithm of the quotient into the difference of the logarithms of the numerator and the denominator. log(z5yx)=log(x)−log(z5y)
Apply Quotient Property Again: Apply the quotient property again to separate log(z5y). We can further expand log(z5y) into log(z5)+log(y) using the product property of logarithms, which states that the logarithm of a product is the sum of the logarithms. log(z5y)=log(z5)+log(y)
Apply Power Property: Apply the power property to log(z5). Using the power property, we can take the exponent out in front of the logarithm. log(z5)=5⋅log(z)
Substitute Expanded Log: Substitute the expanded log(z5) back into the original expression.Now we replace log(z5) in our expression from Step 2 with 5×log(z).log(z5yx)=log(x)−(5×log(z)+log(y))
Distribute Negative Sign: Distribute the negative sign to both terms in the parentheses.We need to apply the negative sign to both log(z5) and log(y).log(z5yx)=log(x)−5⋅log(z)−log(y)
