Question

Answer

Based on the image provided, the problem is as follows:
Problem:
Show that if , then .
Step-by-step Solution:
  1. Start with the given equation:
  2. Use the power property of logarithms, which states that . Apply this to the term :
  3. Recall that is equivalent to :
  4. Express the constant as a logarithm with base . Since , we can substitute:
  5. Use the product property of logarithms, which states that :
  6. Remove the logarithms from both sides (by taking the base exponential of both sides):
Conclusion:
We have shown that if , then .
