Logaritam

Solution

A logarithm is a mathematical concept that helps you solve equations involving exponentiation. It answers the question: "To what exponent must a certain base be raised to produce a given number?"

The General Form

For a given base bb, a logarithm can be written as: logb(a)=x\log_b(a) = x This means that bx=ab^x = a.

Common Types of Logarithms

  1. Common Logarithm (Base 10): log10(x)\log_{10}(x) is often written simply as log(x)\log(x). It's widely used in scientific calculations.
  2. Natural Logarithm (Base ee): loge(x)\log_e(x), written as ln(x)\ln(x), where e2.71828e \approx 2.71828. It's fundamental in calculus and natural growth processes.
  3. Binary Logarithm (Base 2): log2(x)\log_2(x), frequently used in computer science.

Logarithm Properties

  1. Product Rule: logb(xy)=logb(x)+logb(y)\log_b(xy) = \log_b(x) + \log_b(y)
  2. Quotient Rule: logb(xy)=logb(x)logb(y)\log_b\left(\frac{x}{y}\right) = \log_b(x) - \log_b(y)
  3. Power Rule: logb(xc)=clogb(x)\log_b(x^c) = c \cdot \log_b(x)
  4. Change of Base Formula: logb(a)=logc(a)logc(b)\log_b(a) = \frac{\log_c(a)}{\log_c(b)} You can convert logarithms from one base to another using this formula.

log_b(a) = x where b^x = a
log_b(xy) = log_b(x) + log_b(y)
log_b(x/y) = log_b(x) - log_b(y)
log_b(x^c) = c * log_b(x)
log_b(a) = log_c(a) / log_c(b)
