Introduction to the derivative of 3^n

Derivatives have a wide range of applications in almost every field of engineering and science. The 3^n derivative is equal to the product of 3^n and log 3 which can be calculated by following the derivative rules. Or, we can directly find the derivative formula of 3^n by applying the first principle of differentiation. In this article, you will learn what the 3^n derivative formula is and how to calculate the derivatives of 3^n by using different approaches.

What is the derivative of 3^n?

The 3^n derivative is equal to 3^n log 3. It measures the rate of change of the exponential function 3^n. It is denoted by d/dn(3^n) which is a fundamental concept in calculus.

Knowing the formula for derivatives and understanding how to use it can be used in solving problems related to velocity, acceleration, and optimization. 

Derivative of 3^n formula

The formula for derivative of f(x)=3^n is equal to the 3^n log 3, that is;

$f'(x) = \frac{d}{dn} (3^n) = 3^n log 3$

It is calculated by using the logarithmic differentiation.

How do you differentiate 3^n?

There are multiple ways to prove the differentiation of 3 n. These are;

1. First Principle
2. Logarithmic differentiation
3. Quotient Rule

Each method provides a different way to compute the 3^n differentiation. By using these methods, we can mathematically prove the formula for finding the differential of 3^n.

Derivative of 3 power n by first principle

According to the first principle of derivative, the 3^n derivative is equal to 3^n log 3. The derivative of a function by first principle refers to finding a general expression for the slope of a curve by using algebra. It is also known as the delta method. The derivative is a measure of the instantaneous rate of change, which is equal to,

$f’(x) = \lim_{h\to 0}\frac{f(x + h) - f(x)}{h}$

This formula allows us to determine the rate of change of a function at a specific point by using the limit definition of derivative.

Proof of 3^n derivative formula by first principle

To prove the derivative of 3^n by using first principle, replace f(x) by 3^n or you can replace it by 3^n to find the derivative of 2^x. 

$f’(n) = \lim_{h \to 0} \frac{f(n + h) - f(n)}{h}$

$f'(n) = \lim_{h \to 0} \frac{3^{n + h} - 3^n}{h}$

Moreover,

$f'(n) = \lim_{h \to 0} \frac{3^n+3^h-3^n}{h}$

$f'(n) = \lim_{h \to 0} \frac{3^n(3^h-1)}{h}$

When h approaches to zero,

$\lim_{h\to 0}\frac{3^h-1}{h}=\log 3$

And,

$f'(n) = 3^n \log 3$

Hence the 3^n derivative is equal to 3^n log 3. Use our derivative definition calculator with steps to simplify the above calculations easily. 

Derivative of 3^n by Logarithmic Differentiation

Logarithmic derivative is a technique of solving derivatives of logarithmic functions. A logarithmic function is the inverse of an exponential function and can be written using a base of 10. It is a method of finding derivatives of complex functions by applying logarithms.

Proof of differentiating of 3^n by Logarithmic Differentiation

To differentiate of 3^n by using the logarithmic differentiation, we start by assuming that,

$y = 3^x$

Taking log on both sides.

$\log y=\log 3^n$

$\log y=n \log 3$

Now differentiating on the both sides, 

$\frac{d}{dn} (\log y) = \log 3\frac{dn}{dn}$

Since the derivative of log x is equal to the reciprocal of x, therefore, 

$\frac{dy}{dn}.\frac{1}{y}= \log 3$

Hence,

$\frac{dy}{dn} = y\log 3$

Substituting the value of y, we get

$\frac{dy}{dn} = 3^n\log 3$

Hence we can derive the derivative of 3 n by using two derivative rules i.e. delta method and the logarithmic differentiation.
