Quelle est la décomposition correcte de chacun des entiers naturels suivants ?

8457

8\ 457 = \left(7\times 1\ 000\right) +\left(5\times 100\right) + \left(4\times 10\right) +\left(8\times 1\right)

8\ 457 = \left(8\times 100\right) +\left(4\times 10\right) + \left(5\times 1\right) +\left(7\times 0{,}1\right)

8\ 457 = \left(8\times 1\ 000\right) +\left(4\times 100\right) + \left(5\times 10\right) +\left(7\times 1\right)

8\ 457 = \left(8\times 10\ 000\right) +\left(4\times 1\ 000\right) + \left(5\times 100\right) +\left(7\times 10\right)

3782

3\ 782 = \left(2\times 1\ 000\right) +\left(8\times 100\right) + \left(7\times 1\right) +\left(3\times 1\ 000\right)

3\ 782 = \left(3\times 10\ 000\right) +\left(7\times 100\right) + \left(8\times 1\right) +\left(2\times 1\ 000\right)

3\ 782 = \left(3\times 1\ 000\right) +\left(7\times 100\right) + \left(8\times 10\right) +\left(2\times 1\right)

3\ 782 = \left(2\times 10\ 000\right) +\left(8\times 1\ 000\right) + \left(7\times 100\right) +\left(3\times 10\right)

9966

9\ 966 = \left(6\times 1\ 000\right) +\left(9\times 100\right) + \left(6\times 10\right) +\left(9\times 1\right)

9\ 966 = \left(9\times 1\ 000\right) +\left(9\times 100\right) + \left(6\times 10\right) +\left(6\times 1\right)

9\ 966 = \left(9\times 1\ 000\right) +\left(6\times 100\right) + \left(9\times 10\right) +\left(6\times 1\right)

9\ 966 = \left(9\times 10\ 000\right) +\left(9\times 1\ 000\right) + \left(6\times 100\right) +\left(6\times 10\right)

2960

2\ 960 = \left(2\times 10\right) +\left(9\times 1\right) + \left(6\times 0\right)

2\ 960 = \left(2\times 1\ 000\right) +\left(9\times 100\right) + \left(6\times 10\right)

2\ 960 = \left(2\times 10\ 000\right) +\left(9\times 1\ 000\right) + \left(6\times 100\right)

2\ 960 = \left(2\times 100\right) +\left(9\times 10\right) + \left(6\times 1\right)

7063

7\ 063 = \left(7\times 1\ 000\right) + \left(6\times 10\right) +\left(3\times 10\right)

7\ 063 = \left(7\times 1\ 000\right) + \left(6\times 100\right) +\left(3\times 1\right)

7\ 063 = \left(7\times 10\ 000\right) + \left(6\times 100\right) +\left(3\times 10\right)

7\ 063 = \left(7\times 1\ 000\right) + \left(6\times 10\right) +\left(3\times 1\right)

994

994 = \left(9\times 100\right) + \left(9\times 10\right) +\left(4\times 1\right)

994 = \left(9\times 1\ 000\right) + \left(9\times 100\right) +\left(4\times 10\right)

994 = \left(9\times 100\right) + \left(9\times 1\right) +\left(4\times 0\right)

994 = \left(9\times 1\ 000\right) + \left(9\times 100\right) +\left(4\times 1\right)

584

584 = \left(5\times 1\ 000\right) + \left(8\times 100\right) +\left(4\times 1\right)

584 = \left(5\times 100\right) + \left(8\times 10\right) +\left(4\times 1\right)

584 = \left(5\times 1\ 000\right) + \left(8\times 10\right) +\left(4\times 1\right)

584 = \left(5\times 100\right) + \left(8\times 1\right) +\left(4\times 0\right)
