Problem:
Express, as concisely as possible, the value of the product
(03−350)(13−349)(23−348)(33−347)⋯(3493−1)(3503−0) \left(0^{3}-350\right)\left(1^{3}-349\right)\left(2^{3}-348\right)\left(3^{3}-347\right) \cdots\left(349^{3}-1\right)\left(350^{3}-0\right)

A number or a short expression. Fractions can be typed as 3/2, and spacing doesn't matter.

Solution

Solution:
0 . One of the factors is 73−343=07^{3}-343=0, so the whole product is zero.
