It is the first odd prime, and it is equal to the square root of nine.
This value is squared to obtain the larger number in Catalan's conjecture. The Collatz problem multiplies odd inputs by this value, and the Cardano-Tartaglia formula solves equations of this degree. This is the smallest integer power that does not satisfy (*) Fermat's Last Theorem. It is the second triangular number, and the only positive integer to equal the sum of its preceding integers. These many points are necessary to determine a plane and a circle. It is the first odd prime, and it is equal to the square root of nine. For ten points, identify this value, the number of sides in a triangle.
This value is squared to obtain the larger number in Catalan's conjecture.
