Math Problem Statement

2/3log2(3)

Solution

To evaluate the expression:

23log2(3)\frac{2}{3} \log_2(3)

we can proceed as follows:

  1. Interpretation of the Expression:

    • This expression is in the form of a constant 23\frac{2}{3} multiplied by log2(3)\log_2(3), the logarithm of 3 with base 2.
  2. Approximate Value:

    • First, we find log2(3)\log_2(3) approximately. Using the change of base formula:

      log2(3)=log10(3)log10(2)\log_2(3) = \frac{\log_{10}(3)}{\log_{10}(2)}

    • With approximate values for common logarithms: log10(3)0.4771andlog10(2)0.3010\log_{10}(3) \approx 0.4771 \quad \text{and} \quad \log_{10}(2) \approx 0.3010

      log2(3)0.47710.30101.585\log_2(3) \approx \frac{0.4771}{0.3010} \approx 1.585

  3. Multiplying by 23\frac{2}{3}:

    • Now, we multiply by 23\frac{2}{3}:

      23×1.5851.057\frac{2}{3} \times 1.585 \approx 1.057

So, the approximate value of 23log2(3)\frac{2}{3} \log_2(3) is:

1.057\approx 1.057
