A number theory problem

The Tribonacci sequence goes something like this: $0, 1, 1, \ldots$ . We see that the first term is $0$ , hence the product will also be $\boxed{0}$

The first tribonacci number is $0$ , hence the product of the first $10$ tribonacci numbers is $0\times x$ $=$ $\boxed{0}$

The tribonacci numbers are 0, 1, 1... Since 0 is in the sequence, the product of the first x tribonacci numbers is 0.
