Final answer:
To calculate log3(0.5), we rewrite 0.5 as 1/2, use the properties of logarithms and known values to find -log3(2), which is approximately -0.63095.
Step-by-step explanation:
To find log3(0.5), we can use the property of logarithms that states loga(b/c) = logab - logac. The property applies for any base, including base 3. First, notice that 0.5 can be written as 1/2. Therefore, log3(0.5) is the same as log3(1/2), which is log31 - log32.
Since log31 is 0 (because any log base of 1 is 0), what we need to find is -log32. But we were not given log32; we have log34 and log36 instead. We can use the fact that 4 is 22 and express log34 as 2*log32. From the information given, log34 is approximately 1.2619, so log32 is approximately 1.2619 / 2 ≈ 0.63095.
Therefore, log3(0.5) or -log32 is approximately -0.63095.
