WebAug 11, 2015 · Explanation: You can differentiate this function by using the chain rule and the product rule. Notice that your function can be written as y = f (x) ⋅ g(x) which means that its derivative can be determined using the product rule d dx (y) = [ d dx (f (x))] ⋅ g(x) +f (x) ⋅ d dx (g(x)) In your case, f (x) = (1 +4x)5 and g(x) = (3 + x − x2)8. WebNov 2, 2016 · Explanation: Using chain rule, we first find the derivative of the form d dx (√x) = 1 2√x hence, we have, dy dx = 1 2√4x + 3 But, we are not done yet. as we have a term containing x in it inside the square root. Therefore, we differentiate the linear term inside the square root, d dx (4x +3) = 4 Hence our answer is 4 2√4x + 3 = 2 √4x +3 Answer link
