    Also chain rule. Write the square root as (6x+1)^(1/2) and it makes more sense.

    Okay, so you look at it in terms of factors and apply the product rule, so you take the derivative of (3x-5) and multiply by sqrt(6x+1) Then you add that to the product of (3x-5) and the derivative of sqrt(6x+1) also known as first d last plus last d first

    to find the derivative of sqrt(6x+1), rewrite it in the sensible form (6x+1)^(1/2) Bring the exponent down in front, reduce the power by one, then multiply by the derivative of the argument

    so we get (1/2)(6x+1)^(-1/2)(6)

    total is (3x-5)(1/2)(6)(6x+1)^(-1/2)+(3)(6x+1)^(1/2)
