Q. Write the expression below as a single logarithm in simplest form.2logb3−logb3Answer: logb(□)
Understand and Identify: Understand the given expression and identify the logarithm properties to use.We have the expression 2logb3−logb3. To combine these logarithms into a single logarithm, we can use the properties of logarithms, specifically the power rule and the subtraction rule.The power rule states that nlogb(a)=logb(an).The subtraction rule states that logb(a)−logb(c)=logb(a/c).
Apply Power Rule: Apply the power rule to the first term of the expression.Using the power rule, we can rewrite 2logb3 as logb(32).So, 2logb3 becomes logb(9).
Combine Using Subtraction Rule: Combine the two logarithms using the subtraction rule.Now we have logb(9)−logb(3). Using the subtraction rule, we can combine these into a single logarithm:logb(9)−logb(3)=logb(39).
Simplify Fraction: Simplify the fraction inside the logarithm.Simplify 39 to get 3.So, logb(39) becomes logb(3).
