Name the figure below in two different ways

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

Solve the equation w^3 = 1,000 i honestly dont know how to punch this into a calculator pls

What’s the range cuz i can’t find it?
