The derivative of e cube is zero. Note that e cube is written as e3. In this post, we will learn how to find the derivative of e3.
Derivative of e3 Formula
The formula for the derivative of e3 is 0. This formula is written below.
$\dfrac{d}{dx}(e^3)=0$ or $(e^3)’=0$.
Here, the prime $’$ denotes the first-order derivative.
What is the Derivative of e3?
Answer: The derivative of e3 is 0.
Explanation:
It is known that the value of $e$ is given by the following convergent series:
$e=\sum_{n=0}^\infty$ $=1+\dfrac{1}{1!}+\dfrac{1}{2!}+\cdots$
The number e is irrational, and its value is approximately equal to 2.7182818 (up to 7 decimal places). As e is a fixed number, we conclude that e is a constant.
This implies that e3 is a constant with respect to x.
$\therefore \dfrac{d}{dx}(e^3)=0$ by the rule Derivative of a constant is 0.
Thus, the derivative of e3 is equal to 0.

Derivative of e3 by First Principle
Let f(x)=e3. Note that e3 is independent of x, so we have f(x+h)=e3 for any values of x and h. By the first principle, the derivative of f(x)=e3 is equal to
$\dfrac{d}{dx}(f(x))$ $=\lim\limits_{h \to 0} \dfrac{f(x+h)-f(x)}{h}$
So $\dfrac{d}{dx}(e^3)$ $=\lim\limits_{h \to 0} \dfrac{e^3-e^3}{h}$
$=\lim\limits_{h \to 0} \dfrac{0}{h}$
$=\lim\limits_{h \to 0} 0$
$=0$.
Hence, the derivative of e3 by the limit definition is equal to 0.
