$$ \text { Problems 3-8 require the Symbolic Math Toolbox. The others do not. } $$ Compute \(3^{301}\), both as an approximate floating-point number and as an exact integer (written in usual decimal notation).

$$ \text { Problems 3-8 require the Symbolic Math Toolbox. The others do not. } $$ Plot the functions \(x^{4}\) and \(2^{x}\) on the same graph and determine how many times their graphs intersect. (Hint: you will probably have to make several plots, using intervals of various sizes, in order to find all the intersection points.) Now find the approximate values of the points of intersection using fzero.
