Explain how the figure illustrates 6(9)=6(5)+6(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).

Which expression do you get when you eliminate the negative exponents of 4a^2 b^216a^-3 b

Given the expression (7 ? 4i) ? (2 + 6i), perform the indicated operation and write the answer in the form a + bi.
