Subtract. Write your answer in scientific notation. (7.5 * 10^6) - (4.7 * 10^6) Choices: (A)6.7 * 10^0 (B)2.8 * 10^6 (C)6.7 * 10^6 (D)2.8 * 10^0

Identify Coefficients: We have: (7.5 * 10^6) - (4.7 * 10^6) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 7.5 - 4.7? 7.5 - 4.7 = 2.8Convert to Scientific Notation: Write the answer in scientific notation. Substitute 2.8 for a and 6 for b in a * 10^b. Scientific notation: 2.8 * 10^6Find Equivalent Expression: Choose the equivalent expression for (7.5 * 10^6) - (4.7 * 10^6). (7.5 * 10^6) - (4.7 * 10^6) = 2.8 * 10^6 (7.5 * 10^6) - (4.7 * 10^6) is equivalent to 2.8 * 10^6.
