Q. Write the expression below as a single logarithm in simplest form.\newline2logb4 2 \log _{b} 4 \newlineAnswer: logb() \log _{b}(\square)
  1. Question Prompt: Question Prompt: Write the expression 2logb(4)2\log_b(4) as a single logarithm in simplest form.
  2. Identify Property: Identify the property used to write the expression as a single logarithm.\newlineThe Power Property of logarithms states that a coefficient in front of a logarithm can be rewritten as an exponent inside the logarithm. The property is: alogb(x)=logb(xa)a\log_b(x) = \log_b(x^a).
  3. Apply Power Property: Apply the Power Property to the given expression.\newlineUsing the Power Property, we can rewrite 2logb(4)2\log_b(4) as logb(42)\log_b(4^2).
  4. Calculate Exponent: Calculate the exponent. 424^2 equals 1616. So, logb(42)\log_b(4^2) becomes logb(16)\log_b(16).
  5. Write Final Answer: Write the final answer.\newlineThe expression 2logb(4)2\log_b(4) as a single logarithm in simplest form is logb(16)\log_b(16).
