Math Problem Statement

(log(125))/(log(sqrt(5)))

Solution

To simplify log(125)log(5)\frac{\log(125)}{\log(\sqrt{5})}, let's break it down step by step:

  1. Express the numbers in terms of powers of 5:

    • 125=53125 = 5^3
    • 5=51/2\sqrt{5} = 5^{1/2}
  2. Apply logarithmic properties: Using the power rule of logarithms, log(ab)=blog(a)\log(a^b) = b \log(a), we can simplify both the numerator and the denominator.

    • log(125)=log(53)=3log(5)\log(125) = \log(5^3) = 3 \log(5)
    • log(5)=log(51/2)=12log(5)\log(\sqrt{5}) = \log(5^{1/2}) = \frac{1}{2} \log(5)
  3. Substitute these values back into the original expression: log(125)log(5)=3log(5)12log(5)\frac{\log(125)}{\log(\sqrt{5})} = \frac{3 \log(5)}{\frac{1}{2} \log(5)}

  4. Simplify: Cancel out log(5)\log(5) from the numerator and the denominator: 3log(5)12log(5)=312=3×2=6\frac{3 \log(5)}{\frac{1}{2} \log(5)} = \frac{3}{\frac{1}{2}} = 3 \times 2 = 6

Thus, the simplified value is:

6\boxed{6}

Tip: Remember that logarithmic rules apply to any base, not just base 10, as long as the base is consistent.
