log82= \log _{8} 2=

Full solution

Q. log82= \log _{8} 2=
  1. Finding the Logarithm Base: We want to find the value of log82\log_{8}2. This means we are looking for the exponent that 88 must be raised to in order to get 22.
  2. Expressing 88 as a Power of 22: We can express 88 as a power of 22, since 88 is 22 cubed (232^3). This will help us to simplify the logarithm.
  3. Rewriting the Logarithm: Now we rewrite the logarithm using the fact that 88 is 232^3: log(23)2\log_{(2^3)} 2.
  4. Simplifying Using Logarithm Property: Using the property of logarithms that logabc=1bloga(c)\log_{a^b}c = \frac{1}{b} \cdot \log_a(c), we can simplify our expression to 13log22\frac{1}{3} \cdot \log_{2}2.
  5. Determining the Value of log(2)2\log(2)2: We know that log22\log_{2}2 is 11, because 22 raised to the power of 11 is 22.
  6. Calculating the Final Answer: Multiplying 13\frac{1}{3} by 11 gives us the final answer: 13×1=13\frac{1}{3} \times 1 = \frac{1}{3}.
