2,000,000 = (2 x 106) + (0 x 105) + (0 x 104) + (0 x 103) + (0 x 102) + (0 x 101) + (0 x 100)
2x10^6

Expanded Notation of 1,294 = (1 x 103) + (2 x 102) + (9 x 101) + (4 x 100)
Expanded Notation of 1,294 = (1 x 1,000) + (2 x 100) + (9 x 10) + (4 x 1)
8.7329 x 10e3
Expanded Notation of 80 = (8 x 101) + (0 x 100).
10+8+40/10
30,332 in expanded form using powers ten = (3 x 104) + (0 x 103) + (3 x 102) + (3 x 101) + (2 x 100)
Expanded Notation written using the powers of 10 This is an extension of writing the equation in expanded notation! Therefore I will use the information from that to explain; First I'll do out a table showing powers 10^2 = 100 10 to the power of 2 is One Hundred (2 zero's-after the 1) So hopefully you see the pattern in the above table!
81.402 in expanded form using the powers of ten = (8 x 10^1) + (1 x 10^0) + (4/10^1) + (0/10^2) + (2/10^3)
80 is in expanded form. Using exponents, it should be written as 8x10^1 OR 0.8x10^2.
Do you mean 1.9 x 10^4 ?
