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 2784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).

4,768 = (4 x 103) + (7 x 102) + (6 x 101) + (8 x 100)

To write repeated multiplication in an exponential notation, you should write the number that has to be multiplied as the base. Count the number of times that the number is used.

0.8 = 8 × 0.1 = 8 × 1/10

Expanded Notation of 14 = (1 x 10) + (4 x 1)
