The expression 8.59 × 10^4 - 3.2 × 10^3 is equivalent to 82,700 when converted to standard notation. None of the provided options match this value.

Step-by-step explanation:

The expression given is 8.59 × 10^4 - 3.2 × 10^3. To find equivalent values, first the terms need to be converted into standard notation. The first term, 8.59 × 10^4, is equal to 85,900.
