And just to train myself
This should work:
(defn mult-list-by-lists [a b]
(let [mult-lists (fn [x y] (map * x y))]
(map #(mult-lists a %) b)))

Or if you want to avoid the #(...%...) syntax:
user=> (def a (list 1 2 3))
#'user/a
user=> (def b (list '(4 5 6) '(7 8 9)))
#'user/b
user=> (map (partial map * a) b)
((4 10 18) (7 16 27))

#'user/a
user=> (def b [[4 5 6] [7 8 9]])
#'user/b
user=> (map #(map * a %) b)
((4 10 18) (7 16 27))

Clojure make
I want to multiply a list of n items by h lists of n items, so that
for example if i have list 'a' and 'b'
(def a (list 1 2 3))
(def b (list '(4 5 6) '(7 8 9)))
when multiplied I will get:
((4 10 18) (7 16 27))
