Answer» also the chain RULE but with less steps:CONSIDER (2x+1) is any variable and differentiate it the same way as you would differentiate y=x^nWhich is dy/dx = N*x^(n-1)So differentiation the main equation we get,dy/dx= 5*(2x+1)^4 * d(2x+1)/dx[The POINT to be noted here is after differentiating the BRACKET considering it as a variable, we need to again mulply with the differential of the bracket wrt x]So we get,dy/dx= 10*(2x+1)^4And that’s your answer…Do remember the following Chain Rule:dy/dx= (dy/da)* (da/dx)Hope it helps…Feel Good ;) |
