20,351.401 = (2 x 104) + (0 x 103) + (3 x 102) + (5 x 101) + (1 x 100) + (4/101) + (0/102) + (1/103)
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)
1,760 = (1 x 103) + (7 x 102) + (6 x 101) + (0 x 100)
98.364 = (9 x 101) + (8 x 100) + (3/101) + (6/102) + (4/103)
Rewriting a number in its expanded form with exponents helps you to better understand scientific notation. When determining what exponent to use for a power of ten, look at how many zeroes you have. For example, if the number is 1,000, which has three zeroes, it is 10 to the third power.
20,351,401 = (2 x 107) + (0 x 106) + (3 x 105) + (5 x 104) + (1 x 103) + (4 x 102) + (0 x 101) + (1 x 100)
2.5 x 105 = 250,000
