Question: 
Write a function to find the maximum product from the pairs of tuples within a given list.


Model's Code:
def max_product_tuple(tuples_list):
    return max(a * b for a, b in tuples_list)



Sample Correct Code:
def max_product_tuple(list1):
    result_max = max([abs(x * y) for x, y in list1] )
    return result_max


Asserts:
assert max_product_tuple([(2, 7), (2, 6), (1, 8), (4, 9)] )==36
assert max_product_tuple([(10,20), (15,2), (5,10)] )==200
assert max_product_tuple([(11,44), (10,15), (20,5), (12, 9)] )==484
