Remember that each digit in the whole number represents a power of 10:
First take the whole number portion of the number on the left side of the decimal
Expanded Notation of 4598 = (4 x 103) + (5 x 102) + (9 x 101) + (8 x 100)
Expanded Notation of 4598 = (4 x 1000) + (5 x 100) + (9 x 10) + (8 x 1)
Now multiply through and simplify to prove this is the correct notation:
4598 = 4000 + 500 + 90 + 8
4598 = 4598 <---- Correct!
(4 x 1000) + (5 x 100) + (9 x 10) + (8 x 1)
