How do I write 87,192 in expanded form
875,020 = (8 x 10^6) + (7 x 10^5) + (5 x 10^4) + (0 x 10^3) + (0 x 10^2) + (2 x 10^1) + (0 x 10^0)
2.5 x 105 = 250,000
Usually not.
To write a number in expanded form, you first need to divide it by a power of ten such that the greatest place value is units. In this case we can divide by 100 to give 8.26. The next step is to write that power of 10 alongside as a multiplication. 100 is the second power of 10 or 102. Thus 826 in expanded form is 8.26x102

16.5 = (1 x 101) + (6 x 100) + (5/101)
0.492 = (0 x 100) + (4/101) + (9/102) + (2/103)
43 = 64
124 = 20,736
