Step-by-Step Solution

To solve the problem, we employ the property of logarithms for subtraction:

  • Step 1: Recognize the expression log53log52 \log_5 3 - \log_5 2 .
  • Step 2: Apply the logarithmic property for subtraction, logbalogbc=logb(ac) \log_b a - \log_b c = \log_b \left( \frac{a}{c} \right) .
  • Step 3: Substitute into the property: log53log52=log5(32) \log_5 3 - \log_5 2 = \log_5 \left( \frac{3}{2} \right) .

By applying the property, we simplify the expression to log532 \log_5 \frac{3}{2} . This is equivalent to log51.5 \log_5 1.5 . Therefore:

Therefore, the result of the expression is log51.5 \log_5 1.5 .

Answer

log51.5 \log_51.5
