Differentiation Problem

  1. Jul 25, 2011 #1
    1. The problem statement, all variables and given/known data

    (3x+2)^5.(x+1)^-2

    2. Relevant equations

    dy/dx = dy/du . du/dx

    3. The attempt at a solution

    y=(3x+5)^5 . (x+1)^-2

    u = 3x + 5 , du/dx = 3
    v = u^5 , dv/du = 5u^4
    = 15(3x+5)^4

    u = x + 1 , du/dx = 1
    v = u^-2 , dv/du = -2u^-3
    -2(x+1)^-3


    dy/dx = 15(3x+5)^4 . -2(x+1)^-3

    Correct or not? or should I use the Product Rule. . .

    =5(3x+5)^4 .

    Question: Differentiate the following Equation

    ignore the " =5(3x+5)^4 " wrongly type. . .

    It's a product, so you should use the product rule.
