Do the brackets around the equation in part 3(a) (iii) mean that you have to differentiate what is in the brackets first and then apply the chain rule, would you also have to apply the chain rule to the term with the 4ln (7x) in it as well
The brackets are just there to show that the whole expression within is raised to the power . Are you aware of the general rule for differentiating something of the form ?
yeah so its goin to be a chain rule within a chain rule or is it just going to be a straightforward chain rule equation after you assign what is in the brackets to lets say t and then differentiate that
