Answer

The following statements are correct: 1. \( 8^{-2} = \frac{1}{64} \) 2. \( 0 = \log_{6} 1 \) 3. \( \log_{x} x^{4} = 4 \) 5. \( \log_{6}\left(\frac{1}{36}\right) = -2 \) 6. \( 3^{0} = 1 \) 8. \( \frac{1}{25} = 5^{-2} \) 10. \( \left(\frac{1}{2}\right)^{-2} = 4 \) The statement \( 2 = \log_{1} x \) is incorrect because the logarithm base 1 is undefined.

The Deep Dive

Did you know that logarithms can be traced back to the early 17th century? They were invented by John Napier and popularized by the use of logarithmic tables, which made calculations simpler, especially for astronomers and navigators. Logarithms help you convert multiplicative relationships into additive ones, which is a major game-changer in calculations. When using logarithms, it’s easy to confuse the base and the value. A common mistake is writing \(\log_a b = c\) and then flipping \(a, b, c\) around. Remember, it's an equation that maintains the relationship such that \(a^c = b\). Always check that the base is positive and not equal to 1; otherwise, you're headed for trouble!
