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

1609

1\ 609 = \left(1\times 1\ 000\right) +\left(6\times 100\right) +\left(9\times 1\right)

1\ 609 = \left(1\times 1\ 000\right) +\left(6\times 100\right) +\left(9\times 10\right)

1\ 609 = \left(1\times 100\right) +\left(6\times 10\right) +\left(9\times 1\right)

1\ 609 = \left(1\times 10\ 000\right) +\left(6\times 1\ 000\right) +\left(9\times 100\right)

7416

7\ 416 = \left(7\times 1\ 000\right) + \left(4\times 100\right) + \left(6\times 10\right) + \left(1\times 1\right)

7\ 416 = \left(7\times 1\ 000\right) + \left(4\times 10\right) + \left(1\times 100\right) + \left(6\times 1\right)

7\ 416 = \left(7\times 1\ 000\right) + \left(4\times 100\right) + \left(1\times 10\right) + \left(6\times 1\right)

7\ 416 = \left(4\times 1\ 000\right) + \left(7\times 100\right) + \left(1\times 10\right) + \left(6\times 1\right)

1907

1\ 907 = \left(1\times 1\ 000\right) + \left(9\times 100\right) + \left(7\times 1\right)

1\ 907 = \left(1\times 1\ 000\right) + \left(9\times 10\right) + \left(7\times 1\right)

1\ 907 = \left(1\times 1\ 000\right) + \left(9\times 100\right) + \left(7\times 10\right)

1\ 907 = \left(9\times 1\ 000\right) + \left(1\times 100\right) + \left(7\times 1\right)

9297

9\ 297 = \left(9\times 1\ 000\right) + \left(2\times 10\right) + \left(9\times 100\right) + \left(7\times 1\right)

9\ 297 =\left(9\times 1 000\right) +\left(2\times 100\right) + \left(7\times 10\right) + \left(9\times1\right)

9\ 297 = \left(2\times 1\ 000\right) + \left(9\times 100\right) + \left(9\times 10\right) + \left(7\times 1\right)

9\ 297 = \left(9\times 1\ 000\right) + \left(2\times 100\right) + \left(9\times 10\right) + \left(7\times 1\right)

6184

6\ 184 = \left(6\times 1\ 000\right) + \left(1\times 100\right) + \left(8\times 100\right) + \left(4\times 1\right)

6\ 184 = \left(6\times 10\ 000\right) + \left(1\times 100\right) + \left(8\times 10\right) + \left(4\times 1\right)

6\ 184 = \left(6\times 1\ 000\right) + \left(1\times 108\right) + \left(8\times 10\right) + \left(4\times 1\right)

6\ 184 = \left(6\times 1\ 000\right) + \left(1\times 100\right) + \left(8\times 10\right) + \left(4\times 1\right)

707

707 = \left(7\times 100\right) + \left(1\times 10\right) + \left(7\times 1\right)

707 = \left(7\times 100\right) + \left(7\times 1\right)

707 = \left(7\times 10\right) + \left(7\times 1\right)

707 = \left(7\times 100\right) + \left(7\times 10\right) + \left(7\times 1\right)
