Q. Given the function f(x)=(6+10x3)(8x310+8x) f(x)=\left(6+10 x^{3}\right)\left(8 x^{3}-10+8 x\right) , find f(x) f^{\prime}(x) in any form.\newlineAnswer: f(x)= f^{\prime}(x)=
  1. Product Rule Explanation: To find the derivative of the function f(x)=(6+10x3)(8x310+8x)f(x)=(6+10x^{3})(8x^{3}-10+8x), we will use the product rule. The product rule states that the derivative of a product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function.
  2. Denote Functions: Let's denote the first function as u(x)=6+10x3u(x) = 6+10x^{3} and the second function as v(x)=8x310+8xv(x) = 8x^{3}-10+8x. We will find the derivatives of u(x)u(x) and v(x)v(x) separately.
  3. Derivative of u(x)u(x): The derivative of u(x)=6+10x3u(x) = 6+10x^{3} with respect to xx is u(x)=0+30x2u'(x) = 0 + 30x^{2}, since the derivative of a constant is 00 and the derivative of x3x^{3} is 3x23x^{2} multiplied by the coefficient 1010.
  4. Derivative of v(x)v(x): The derivative of v(x)=8x310+8xv(x) = 8x^{3}-10+8x with respect to xx is v(x)=24x2+0+8v'(x) = 24x^{2} + 0 + 8, since the derivative of x3x^{3} is 3x23x^{2} multiplied by the coefficient 88, the derivative of a constant is 00, and the derivative of xx is 11 multiplied by the coefficient 88.
  5. Apply Product Rule: Now we apply the product rule: f(x)=u(x)v(x)+u(x)v(x)f'(x) = u'(x)v(x) + u(x)v'(x). Substituting the derivatives we found, we get f(x)=(30x2)(8x310+8x)+(6+10x3)(24x2+8)f'(x) = (30x^{2})(8x^{3}-10+8x) + (6+10x^{3})(24x^{2}+8).
  6. Expand Terms: We will now expand the terms: f(x)=240x5300x2+240x3+144x2+240x5+80xf'(x) = 240x^{5} - 300x^{2} + 240x^{3} + 144x^{2} + 240x^{5} + 80x.
  7. Combine Like Terms: Combine like terms to simplify the expression: f(x)=240x5+240x5+240x3300x2+144x2+80xf'(x) = 240x^{5} + 240x^{5} + 240x^{3} - 300x^{2} + 144x^{2} + 80x.
  8. Final Answer: After combining like terms, we get f(x)=480x5+240x3156x2+80xf'(x) = 480x^{5} + 240x^{3} - 156x^{2} + 80x.
  9. Final Answer: After combining like terms, we get f(x)=480x5+240x3156x2+80xf'(x) = 480x^{5} + 240x^{3} - 156x^{2} + 80x.We have found the derivative of the function f(x)f(x) in its simplified form. The final answer is f(x)=480x5+240x3156x2+80xf'(x) = 480x^{5} + 240x^{3} - 156x^{2} + 80x.
