Haskell — Usage of higher-order functions (1)

Implement the following functions using higher-order functions (and
other predefined functions) of Haskell without using recursion.

1.  Implement a function eql :: [Int] -> [Int] -> Bool that tells wether
    two lists of integers are equal.

2.  Implement a function prod :: [Int] -> Int that returns the product
    of a list of integers.

3.  Implement a function prodOfEvens :: [Int] -> Int that returns the
    product of all even numbers of a list of integers.

4.  Implement a function powersOf2 :: [Int] that generates the list of
    all the powers of 2.

5.  Implement a function scalarProduct :: [Float] -> [Float] -> Float
    that returns the dot product of two lists of float numbers with the
    same size.

Scoring

Each function scores 20 points.
