I am stuck on that one too sorry.

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

Here is the correct defenition: Algebraic Expression is an expression which is obtained by performing a finite number of the following operations on symbols representing numbers: addition, subtraction, multiplication, division, raising to a power.

Superscript or e notation. 5 to the 3rd power is written as 5 with superscript 3. e notation is for multiplication by powers of 10. So 4 times 10 to the 6'th power (4 million) is 4e6 in e notation.
