Derivative of Exponential Functions: Finding d(4e^5x)/dx

Click For Summary
SUMMARY

The derivative of the function d(4e^5x)/dx is calculated using the chain rule. The correct formula to apply is [a^f(x)]' = log(a) a^f(x) f'(x). In this case, the derivative simplifies to 20e^5x, where the constant 4 is multiplied by the derivative of the exponent 5x. The initial attempts presented in the discussion were incorrect, emphasizing the importance of correctly applying differentiation rules.

PREREQUISITES
  • Understanding of basic calculus concepts, specifically differentiation.
  • Familiarity with the chain rule in calculus.
  • Knowledge of exponential functions and their properties.
  • Ability to apply logarithmic differentiation techniques.
NEXT STEPS
  • Study the chain rule in detail, focusing on its application to exponential functions.
  • Practice differentiation of composite functions using various examples.
  • Explore logarithmic differentiation and its advantages in complex derivatives.
  • Review the properties of exponential functions to strengthen foundational knowledge.
USEFUL FOR

Students studying calculus, educators teaching differentiation techniques, and anyone seeking to improve their understanding of exponential function derivatives.

Homework Statement



d(4e^5x)/dx


The Attempt at a Solution



e5x(4e5x-1)(e5x)

or

(4e^5x)(ln4)

I found the above using two different methods. I don't know if either is right.
It is entirely possible that both are wrong.

Those are both wrong. You need to use the chain rule. Start with the exponential rule
[a^f(x)]'=log(a) a^f(x) f'(x)
