Look again at the Newton-Raphson method which can be used to numerically approximate cube roots x of a number y. The fourth root can be approximated in a similar way: xn+1=31[2xn+xn2y] xn+1=41[3xn+xn3y] Cube root Fourth root Adapt your design and code for tutorial 3 question 3 to use Newton Raphson in two functions: one which estimate the cube root of a number provided by an input argument, and one which estimates the fourth root. Package your functions in a module, and design and write some code to let the user calculate the cube and 4th roots of a number of their choice. Stretch goal: if you can see a pattern in the formulae, add a function to calculate the nth root to your module, and let the user use it. You don't need to demonstrate this to satisfy this week's requirements
