Write 2100 as an exponent with a base of 4

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).

Question and answers are in the attached picture. you so much in advance.

The product of two negative rational numbers is always zero sometimes zero never zero
