3 <p>The derivative of root 3x, expressed as (3x)^(1/2), is used to analyze how this function changes in response to small changes in x. Derivatives are crucial in calculating rates of change in various real-life situations. We will now discuss the derivative of root 3x in detail.</p>

4 <h2>What is the Derivative of Root 3x?</h2>

5 <p>The derivative<a>of</a>root 3x is commonly represented as d/dx [(3x)^(1/2)] or [(3x)^(1/2)]', and its value is (3/2)(3x)^(-1/2). The<a>function</a>(3x)^(1/2) has a clearly defined derivative, indicating it is differentiable within its domain. The key concepts are mentioned below: Square Root Function: ((3x)^(1/2) indicates the<a>square</a>root of 3x). Power Rule: Rule for differentiating (3x)^(1/2).</p>

6 <h2>Derivative of Root 3x Formula</h2>

7 <p>The derivative of root 3x can be denoted as d/dx [(3x)^(1/2)] or [(3x)^(1/2)]'. The<a>formula</a>used to differentiate root 3x is: d/dx [(3x)^(1/2)] = (3/2)(3x)^(-1/2) The formula applies to all x where x > 0.</p>

8 <h2>Proofs of the Derivative of Root 3x</h2>

9 <p>We can derive the derivative of root 3x using proofs. To show this, we will use the rules of differentiation. There are several methods we use to prove this, such as: By First Principle Using Chain Rule Using the Power Rule We will now demonstrate that the differentiation of (3x)^(1/2) results in (3/2)(3x)^(-1/2) using the above-mentioned methods: By First Principle The derivative of (3x)^(1/2) can be proved using the First Principle, which expresses the derivative as the limit of the difference<a>quotient</a>. To find the derivative of (3x)^(1/2) using the first principle, we will consider f(x) = (3x)^(1/2). Its derivative can be expressed as the following limit. f'(x) = limₕ→₀ [f(x + h) - f(x)] / h … (1) Given that f(x) = (3x)^(1/2), we write f(x + h) = (3(x + h))^(1/2). Substituting these into<a>equation</a>(1), f'(x) = limₕ→₀ [(3(x + h))^(1/2) - (3x)^(1/2)] / h Using<a>binomial</a>expansion and simplification, f'(x) = (3/2)(3x)^(-1/2). Hence, proved. Using Chain Rule To prove the differentiation of (3x)^(1/2) using the chain rule, Let u = 3x, then f(x) = u^(1/2). By the chain rule, d/dx [u^(1/2)] = (1/2)u^(-1/2) * (du/dx). Since du/dx = 3, d/dx [(3x)^(1/2)] = (1/2)(3x)^(-1/2) * 3 = (3/2)(3x)^(-1/2). Using the Power Rule We will now prove the derivative of (3x)^(1/2) using the<a>power</a>rule. f(x) = (3x)^(1/2) can be expressed as (3x)^0.5. Using the power rule, d/dx [u^n] = n*u^(n-1) * (du/dx). We have u = 3x, n = 0.5, and du/dx = 3. d/dx [(3x)^(1/2)] = 0.5*(3x)^(-0.5) * 3 = (3/2)(3x)^(-1/2).</p>

12 <h2>Higher-Order Derivatives of Root 3x</h2>

11 <h2>Higher-Order Derivatives of Root 3x</h2>

13 <p>When a function is differentiated several times, the derivatives obtained are referred to as higher-order derivatives. Higher-order derivatives can be a little tricky. To understand them better, think of a car where the speed changes (first derivative) and the<a>rate</a>at which the speed changes (second derivative) also changes. Higher-order derivatives make it easier to understand functions like (3x)^(1/2). For the first derivative of a function, we write f′(x), which indicates how the function changes or its slope at a certain point. The second derivative is derived from the first derivative, which is denoted using f′′(x). Similarly, the third derivative, f′′′(x), is the result of the second derivative, and this pattern continues. For the nth Derivative of (3x)^(1/2), we generally use fⁿ(x) for the nth derivative of a function f(x), which tells us the change in the rate of change (continuing for higher-order derivatives).</p>
