Solution

The statements you've shared appear to be a mix of logarithmic properties and identities. I will clarify them and restate the correct logarithmic rules based on your input.

  1. loga1=0\log_a 1 = 0

    • This is true because any logarithm of 1, regardless of the base, is always 0.
  2. logax=1\log_a x = 1 when x=ax = a

    • This means that the logarithm of a number xx in base aa is 1 if and only if x=ax = a. For example, log22=1\log_2 2 = 1.
  3. logx=log10x\log x = \log_{10} x

    • This indicates that if no base is specified, it is implied to be base 10 (common logarithm).
  4. Product Rule: loga(xy)=logax+logay\log_a (x \cdot y) = \log_a x + \log_a y

    • When multiplying numbers inside a logarithm, you can separate them into a sum of two logarithms.
  5. Quotient Rule: loga(xy)=logaxlogay\log_a \left( \frac{x}{y} \right) = \log_a x - \log_a y

    • When dividing numbers inside a logarithm, you can separate them into a difference of two logarithms.
  6. Multiple Terms: loga(xxyyz)=logaz\log_a (x \cdot x \cdot y \cdot y \cdot z) = \log_a z

    • This could be interpreted as combining multiple terms into one logarithm, though the logic might be unclear without more context.
  7. Power Rule: loga(xn)=nlogax\log_a (x^n) = n \cdot \log_a x

    • When raising a number inside a logarithm to a power, you can pull the exponent out in front.
  8. Logarithmic Base and Power Rule:
    loganx=1nlogax\log_{a^n} x = \frac{1}{n} \cdot \log_a x

    • If the base of a logarithm is raised to a power nn, you can factor out 1n\frac{1}{n}.
  9. Another Power Rule:
    logan(xm)=mnlogax\log_{a^n} (x^m) = \frac{m}{n} \cdot \log_a x

    • This is a generalization of the previous rule combining both powers inside and outside the logarithm.
  10. Change of Base Formula:
    logax=logbxlogba\log_a x = \frac{\log_b x}{\log_b a}

  • This is the change of base formula, which allows you to change the base of a logarithm to another base bb.
  1. logax1 if xa\log_a x \neq 1 \text{ if } x \neq a
  • This is stating that logax\log_a x will not equal 1 unless x=ax = a.
  1. Exponent-Log Rule:
    alogax=xa^{\log_a x} = x
  • This is the inverse property of logarithms. If a number is raised to its own logarithmic base, the result is xx.

Do you have any specific questions about these properties or would you like further clarification on one of them?
