Hi guys i need in these two or one i will post one by one me in these .im so confused

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).

Write the equation in logarithmic form 8^x=64

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)
