Math Problem Statement

Write the log equation as an exponential equation. You do not need to solve for x. log_{(x-4)}(3x) = 3

Solution

The given equation is:

log(x4)(3x)=3\log_{(x-4)}(3x) = 3

To write this logarithmic equation in exponential form, we use the general rule for converting logarithmic equations to exponentials:

logb(a)=cis equivalent tobc=a\log_b(a) = c \quad \text{is equivalent to} \quad b^c = a

In this case:

  • b=x4b = x - 4 (the base of the logarithm),
  • a=3xa = 3x (the argument inside the logarithm), and
  • c=3c = 3 (the right-hand side of the equation).

Thus, the exponential form of the equation is:

(x4)3=3x(x - 4)^3 = 3x

  2. What is the significance of logarithmic and exponential relationships in real-life applications?
  3. How can you determine the domain of a logarithmic function like log(x4)(3x)\log_{(x-4)}(3x)?
  4. Can you explain how to expand (x4)3(x - 4)^3 using the binomial theorem?
  5. How do logarithmic equations change if the base is a constant like 10 instead of a variable?

Tip: Remember, logarithms and exponentials are inverses of each other, which makes converting between the two quite straightforward!
