Q. Given the function \newliney=6+x45x2y=\frac{6+x^{4}}{5x-2}, find \newlinedydx\frac{dy}{dx} in simplified form.
  1. Identify function: Identify the function to differentiate.\newlineWe are given the function y=6+x45x2y=\frac{6+x^{4}}{5x-2}. We need to find the derivative of this function with respect to xx, which is denoted as dydx\frac{dy}{dx}.
  2. Apply quotient rule: Apply the quotient rule for differentiation.\newlineThe quotient rule states that the derivative of a function in the form of u(x)/v(x)u(x)/v(x) is given by (v(x)u(x)u(x)v(x))/(v(x))2(v(x) \cdot u'(x) - u(x) \cdot v'(x)) / (v(x))^2, where u(x)u(x) is the numerator and v(x)v(x) is the denominator of the function.
  3. Differentiate numerator and denominator: Differentiate the numerator and the denominator separately.\newlineThe numerator u(x)=6+x4u(x) = 6 + x^4, and its derivative u(x)u'(x) is 0+4x30 + 4x^3.\newlineThe denominator v(x)=5x2v(x) = 5x - 2, and its derivative v(x)v'(x) is 55.
  4. Apply quotient rule with derivatives: Apply the quotient rule using the derivatives from Step 33.\newlinedydx=(5x2)(4x3)(6+x4)5(5x2)2\frac{dy}{dx} = \frac{(5x - 2) \cdot (4x^3) - (6 + x^4) \cdot 5}{(5x - 2)^2}
  5. Expand numerator: Expand the numerator of the derivative. dydx=20x48x35x430(5x2)2\frac{dy}{dx} = \frac{20x^4 - 8x^3 - 5x^4 - 30}{(5x - 2)^2}
  6. Combine like terms: Combine like terms in the numerator.\newlinedydx=15x48x330(5x2)2\frac{dy}{dx} = \frac{15x^4 - 8x^3 - 30}{(5x - 2)^2}
  7. Simplify derivative expression: Simplify the derivative expression if possible.\newlineThe expression is already simplified, so this is the final form of the derivative.\newlinedydx=15x48x330(5x2)2\frac{dy}{dx} = \frac{15x^4 - 8x^3 - 30}{(5x - 2)^2}
