Expanded Notation of 2784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).
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
You can get from 6 to 18 using multiplication by multiplying it by 3!
Using multiplication 40 times 45 = 1800

I am stuck on that one too sorry.

220.02 = 2 × 100 + 2 × 10 + 2 × 0.01
(1 x 100) + (2 x 10) + (0 x 1) . (0/10) + (0/100) + (3/1000)

I memorized the multiplication table in fourth grade.
