Racket language problems

Please solve number b ( an example is given) . Racket evaluates each expression from top-to-bottom, left-to-right

Given the following expression (8-4(6-13) gvell expression in Racket and bind it to variable exi (b) (3.5 points) Implement the sequence of evaluations of the given expression down to a value and bind that list to variable ex2, as we learned in Lecture 1. For instance, for expression 3.14159 (10 x d) you would write the following term. (define ex2 (list 3.14159 10 10)) 3.14159 100) 314.159))
