Introduction to the derivative of 6^x

Derivatives have a wide range of applications in almost every field of engineering and science. The 6^x derivative is equal to the product of 6^x and log 6 which can be calculated by following the differential rules. Or, we can directly find the derivative formula of 6^x by applying the first principle of differentiation. In this article, you will learn what the 6^x derivative formula is and how to calculate the derivatives of 6^x by using different approaches.

What is the derivative of 6^x?

The derivative of 6^x is equal to 6^x log 6. It measures the rate of change of the exponential function 6^x. It is denoted by d/dx(6^x) 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 6^x formula

The formula for derivative of f(x)=6^x is equal to the 6^x log 6, that is;

$f'(x) = \frac{d}{dx} (6^x) = 6^x log 6$

It is calculated by using the logarithmic differentiation.

How do you differentiate 6^x?

There are multiple ways to prove the differentiation of 6 x. These are;

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

Each method provides a different way to compute the 6^x differentiation. By using these methods, we can mathematically prove the formula for finding the differential of 6^x.

Derivative of 6 power x by first principle

According to the first principle of derivative, the 6^x derivative is equal to 6^x log 6. 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 6^x derivative formula by first principle

To prove the derivative of 6^x by using first principle, replace f(x) by 6^x or you can replace it by 6^x to find the derivative of 2^x

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

$f'(x) = \lim_{h \to 0} \frac{6^{x + h} - 6^x}{h}$


$f'(x) = \lim_{h \to 0} \frac{6^x+6^h-6^x}{h}$

$f'(x) = \lim_{h \to 0} \frac{6^x(6^h-1)}{h}$

When h approaches to zero,

$\lim_{h\to 0}\frac{6^h-1}{h}=\log 6$


$f'(x) = 6^x \log 6$

Hence the differentiation of 6 x is equal to 6^x log 6. Use our derivative by definition calculator to simplify the above calculations easily. 

Derivative of 6^x by Logarithmic Differentiation

Logarithmic differentiation 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 6^x by Logarithmic Differentiation

To differentiate of 6^x by using the logarithmic differentiation, we start by assuming that,

$y = 6^x$

Taking log on both sides.

$\log y=\log 6^x$

$\log y=x \log 6$

Now differentiating on the both sides, 

$\frac{d}{dx} (\log y) = \log 6\frac{dx}{dx}$

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

$\frac{dy}{dx}.\frac{1}{y}= \log 6$


$\frac{dy}{dx} = y\log 6$

Substituting the value of y, we get

$\frac{dy}{dx} = 6^x\log 6$

Hence we can derive the derivative of 6 x by using two derivative rules i.e. delta method and the logarithmic differentiation.
