To calculate the expression, we subtract the numbers in scientific notation separately and then convert the result back to scientific notation:

6.25 x 10^6 - 4.73 x 10^6

= (6.25 - 4.73) x 10^6

= 1.52 x 10^6

Therefore, the answer expressed in scientific notation to 2 decimal places would be 1.52 x 10^6.
