Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx,logy, and logz.logz3y2x5Answer:
Apply Quotient Rule: We start by applying the quotient rule of logarithms, which states that log(ba)=log(a)−log(b). In this case, we have a=x5 and b=z3y2.
Apply Power Rule: Next, we apply the power rule of logarithms, which states that log(ab)=b⋅log(a). For the numerator, we have x5 which is x5/2, and for the denominator, we have z3 and y2.
Rewrite Using Product Rule: We can now rewrite the logarithm as log(x25)−(log(z3)+log(y2)) by applying the product rule of logarithms, which states that log(ab)=log(a)+log(b), to the denominator.
Apply Power Rule: We apply the power rule to each term: log(x25) becomes 25⋅log(x), log(z3) becomes 3⋅log(z), and log(y2) becomes 2⋅log(y).
Subtract Logs: Subtracting the logs in the denominator from the log in the numerator, we get (25)log(x)−3log(z)−2log(y).
Final Expanded Form: This is the fully expanded form of the original logarithm in terms of logx, logy, and logz.
