Simplifying Logarithmic Expressions: ln(e³ ln(e²y))

In mathematics, logarithms are used to simplify complex expressions involving powers and exponents. Logarithmic expressions can often be simplified by applying specific rules and properties. This article aims to provide a comprehensive guide on simplifying the logarithmic expression ln(e³ ln(e²y)).

Key Concepts

1. Definition of Logarithm:

A logarithm is the exponent to which a base must be raised to obtain a given number. In other words, logₐ(b) = c if a^c = b.

2. Logarithmic Properties:

  • Logarithm of a Number: ln(a) = logₑ(a)
  • Logarithm of a Product: ln(ab) = ln(a) + ln(b)
  • Logarithm of a Quotient: ln(a/b) = ln(a) – ln(b)
  • Logarithm of a Power: ln(a^r) = r ln(a)

Simplifying ln(e³ ln(e²y))

1. Simplifying the Inner Logarithm:

ln(e²y) = 2y (by the ln(a^r) property)

2. Substituting the Simplified Expression:

ln(e³(2y)) = ln(2e³y) (by the ln(ab) property)

3. Applying the ln(a^r) Property:

ln(2e³y) = ln(2) + ln(e³y)

4. Simplifying the Exponent:

e³ = e³ (since the base is e)

5. Applying the ln(ab) Property:

ln(2) + ln(e³y) = ln(2) + 3ln(y) (by the ln(a^r) property)

Final Simplified Expression

Therefore, ln(e³ ln(e²y)) simplifies to:

ln(2) + 3ln(y)
