Answer 1

(define (sum a b) (+ a b))
(define (square a) (* a a))
(define (greater a b ) 
  ( if (< a b) b a))
(define (smaller a b ) 
  ( if (< a b) a b))
(define (sumOfSquare a b)
    (sum (square a) (square b)))
(define (sumOfSquareOfGreaterNumbers a b c)
  (sumOfSquare (greater a b) (greater (smaller a b) c)))
