SUMMARY

The equation e^(-1) = c can be rewritten in logarithmic form as -1 = ln(c). This transformation utilizes the natural logarithm, where ln(e^(-1)) simplifies to -1. The discussion highlights the fundamental relationship between exponential and logarithmic functions, specifically that y = a^x is equivalent to log_a(y) = x. Understanding these concepts is crucial for solving logarithmic equations effectively.

PREREQUISITES
  • Understanding of exponential functions
  • Familiarity with natural logarithms (ln)
  • Basic algebra skills
  • Knowledge of logarithmic identities
NEXT STEPS
  • Study the properties of natural logarithms
  • Learn how to solve exponential equations
  • Explore logarithmic identities and their applications
  • Practice converting between exponential and logarithmic forms
USEFUL FOR

Students studying mathematics, educators teaching logarithmic concepts, and anyone looking to strengthen their understanding of exponential and logarithmic relationships.

Rewrite in logarithmic form:

e^(-1) = c
 
Mathematics news on Phys.org
$$\ln\left(e^{-1}\right)=\ln(c)$$

$$-1=\ln(c)$$
 
thanks
 
You have posted a number of logarithm problems without, apparently, know what a "logarithm" is! If you are not taking a class that involves logarithms, where are you getting these problems?

$y= a^x$ is equivalent to $log_a(y)= x$.
