power.
Nine to the fourth power is written as 94, and is expanded as 9 x 9 x 9 x 9.
1.72 x 104 is 17200 when expanded as 1.72 x 104 is already in standard notation.
3 x 10^3 +1 x 10^1 +8
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
