    Hey aayushmail007.

    Do you have to simply apply the Newton-Rhapson method to find the value of a (a good enough approximation)?

    Try expanding the (1+a)^n terms using the binomial method and then simplify these by noting that - 1 takes away the +1 term.

    Re: Not able to solve following

    Try looking up solutions using Newton-Rhapson to solve implicit functions.

    You can get the derivative by using implicit differentiation and you should get a function of a equal to zero where f(a) = 0 and this is done by some standard algebra.

    Once you have this equal to zero then use a root finding algorithm to get your value for a.
