Calculate 6.25 x 10^6 - 4.73 × 10^6
To subtract the numbers, we need to ensure that the exponents are the same.
We start by writing 6.25 × 10^6 and 4.73 × 10^6 in scientific notation:
6.25 × 10^6 = 6.25 × 1,000,000 = 6,250,000
Subtract 4.73 × 10^6 from 6.25 × 10^6:
6,250,000 - 4,730,000 = 1,520,000
Therefore, 6.25 × 10^6 - 4.73 × 10^6 = 1.52 × 10^6.
