<p>We can derive the derivative of 3√x using proofs. To show this, we will use the power rule along with the rules of differentiation. There are several methods we use to prove this, such as: By First Principle Using Power Rule Using Constant Multiple Rule We will now demonstrate that the differentiation of 3√x results in (3/2)x^(-1/2) using the above-mentioned methods: By First Principle The derivative of 3√x 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 3√x using the first principle, we will consider f(x) = 3√x. Its derivative can be expressed as the following limit. f'(x) = limₕ→₀ [f(x + h) - f(x)] / h … (1) Given that f(x) = 3√x, we write f(x + h) = 3√(x + h). Substituting these into<a>equation</a>(1), f'(x) = limₕ→₀ [3√(x + h) - 3√x] / h = 3 limₕ→₀ [√(x + h) - √x] / h Multiply by the<a>conjugate</a>to simplify: = 3 limₕ→₀ [(x + h - x) / h(√(x + h) + √x)] = 3 limₕ→₀ h / [h(√(x + h) + √x)] = 3 limₕ→₀ 1 / (√(x + h) + √x) = 3/(2√x) As x approaches 0, the<a>expression</a>simplifies to (3/2)x^(-1/2). Using Power Rule To prove the differentiation of 3√x using the power rule, We use the formula: 3√x = 3x^(1/2) Using the power rule: d/dx [x^n] = n*x^(n-1) d/dx (3x^(1/2)) = 3 * (1/2) * x^(-1/2) = (3/2) * x^(-1/2) Using Constant Multiple Rule We will now prove the derivative of 3√x using the constant<a>multiple</a>rule. The step-by-step process is demonstrated below: Here, we use the formula, 3√x = 3 * x^(1/2) Using the constant multiple rule where d/dx [c*f(x)] = c*f'(x), d/dx (3√x) = 3 * d/dx (x^(1/2)) Using the power rule: d/dx (x^(1/2)) = (1/2) * x^(-1/2) So, d/dx (3√x) = 3 * (1/2) * x^(-1/2) = (3/2) * x^(-1/2)</p>

<h2>Higher-Order Derivatives of 3 Square Root of x</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 3√x. 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 3√x, 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>
