Math Problem Statement

Evaluate \( \log_{64} 32 \)

Solution

To evaluate log64(32)\log_{64}(32), we need to find the power to which 64 must be raised to get 32.

Solution:

  1. Express 64 and 32 in terms of powers of 2:

    • 64=2664 = 2^6
    • 32=2532 = 2^5
  2. Rewrite log64(32)\log_{64}(32) using these powers of 2: log64(32)=log26(25)\log_{64}(32) = \log_{2^6}(2^5)

  3. Use the change of base formula: log26(25)=56\log_{2^6}(2^5) = \frac{5}{6}

Conclusion:

log64(32)=56\log_{64}(32) = \frac{5}{6}
