1.5 x 108
To express a number in expanded notation, you first need to divide it by a power of 10 such that the units is the greatest place value. In this case, you would divide by 100 to get 8.523. The next step is to add that power of ten to the sum as a multiplication. We use 100, which is the second power of 10. This can be written as 102. Thus 852.3 can be written in expanded notation as 8.523x102
Expanded Notation of 525 = (5 x 102) + (2 x 101) + (5 x 100).
Expanded Notation of 642,275 = (6 x 100,000) + (4 x 10,000) + (2 x 1,000) + (2 x 100) + (7 x 10) + (5 x 1)
10 + 0.01 + 0.005
The Expanded Form (Notation) of 10 = (1 x 101) + (0 x 100)
It is 2000 + 30 + 2 and in base ten, that is 2032.
1.2 times ten to the fifth power in decimal notation is 120,000
Expanded Notation of 1,294 = (1 x 103) + (2 x 102) + (9 x 101) + (4 x 100)
In expanded notation you would write the number 42,166,037 as: 40,000,000 + 2,000,000 + 100,000 + 60,000 + 6,000 + 30 + 7.
Expanded Notation of 1,294 = (1 x 1,000) + (2 x 100) + (9 x 10) + (4 x 1)
.59 times ten to the power of ten
