In a table used to convert from decimal to binary, the top row would typically represent the powers of 2, because binary is a base-2 numbering system. The powers of 2 would be:
(which equals 1) (which equals 2) (which equals 4) (which equals 8) (which equals 16)- And so on.
Given the options you provided:
- 1 (which is
) - 2 (which is
) - 10 (not a power of 2)
- 2 x 10 (not a power of 2)
So the appropriate options from the given choices would be 1 and 2.
