236 = (2 x 10^2) + (3 x 10^1) + (6 x 10^0)
841 = (8 x 10^2) + (4 x 10^1) + (1 x 10^0)
(3 x 100) + (7/101) + (5/102)
625 can be written as 6.25 × 102 in scientific notation or expanded form as (6 x 102) + (2 x 101) + (5 x 100)
I would say they are in standard form, but I would be more likely just to ask you to write a simplified number without using exponents. The terminology can vary, but the following example shows the usual names: 1,023 is in standard form. One thousand twenty-three is in word form. 1000 + 20 + 3 is in expanded form.
80 is in expanded form. Using exponents, it should be written as 8x10^1 OR 0.8x10^2.

640 written in expanded form using exponents is (6 x 10^2) + (4 x 10^1) + (0 x 10^0)
The expanded form of 781.003 using exponents is (7 x 102) + (8 x 101) + (1 x 100) + (0/101) + (0/102) + (3/103)
898,043 in expanded form using exponents is (8 x 105) + (9 x 104) + (8 x 103) + (0 x 102) + (4 x 101) + (3 x 100)
658 in expanded form using exponents is (6 x 102) + (5 x 101) + (8 x 100)
You write 102,436 in expanded form using exponents as: (1 x 105) + (0 x 104) + (2 x 103) + (4 x 102) + (3 x 101) + (6 x 100).
