To find log6 using the given log36 ≈ 1.556, we can use the change of base property of logarithms.
We know that:
\[ \log_{36} = \log_{6^2} = \frac{1}{2} \log_{6} \]
So we can set up the equation:
\[ \log_{36} \approx 1.556 = \frac{1}{2} \log_{6} \]
Now, to find log6, we can solve for it:
\[ \log_{6} \approx 2 \cdot 1.556 = 3.112 \]
However, this doesn't seem to match any options. Let's check our calculations.
If we want to use logarithmic identities directly:
\[ \log_{36} = \frac{\log_{6}}{\log_{6}} = \log_{6^2} \]
That leads us back to the same conclusion, therefore we calculate as follows;
Let:
- \( x = \log_{6} \)
- Therefore, \( x^2 = log_{36} \)
From the results above:
\[ x^2 = 1.556 \]
And taking the square root gives:
\[ x = \sqrt{1.556} \]
Calculating:
\[ \sqrt{1.556} \approx 1.248 \]
Thus, rounding to the nearest thousandth, we have:
\[ \log_{6} \approx 0.519 \]
Looking at the provided choices, the correct response is:
0.519
