To subtract these numbers, we must have the same exponent for 10. Therefore, we can rewrite 6.25 x 10^6 as 625 x 10^4 and 4.73 x 10^6 as 473 x 10^4.
Subtracting these numbers, we get:
625 x 10^4 - 473 x 10^4 = (625 - 473) x 10^4 = 152 x 10^4
To express this answer in scientific notation, we can rewrite 152 as 1.52 x 10^2. Thus, the final answer is:
1.52 x 10^2 x 10^4 = 1.52 x 10^(2+4) = 1.52 x 10^6
Subtracting these numbers, we get:
625 x 10^4 - 473 x 10^4 = (625 - 473) x 10^4 = 152 x 10^4
To express this answer in scientific notation, we can rewrite 152 as 1.52 x 10^2. Thus, the final answer is:
1.52 x 10^2 x 10^4 = 1.52 x 10^(2+4) = 1.52 x 10^6
