Q. Subtract. Write your answer in scientific notation.\newline(7.5×106)(4.7×106)(7.5 \times 10^6) - (4.7 \times 10^6)\newlineChoices:\newline(A) 2.8×1002.8 \times 10^0\newline(B) 6.7×1006.7 \times 10^0\newline(C) 2.8×1062.8 \times 10^6\newline(D) 6.7×1066.7 \times 10^6
  1. Identify Subtraction Problem: We have the following subtraction problem:\newline(7.5×106)(4.7×106)(7.5 \times 10^6) - (4.7 \times 10^6)\newlineSince the powers of 1010 are the same, we can directly subtract the coefficients.\newlineWhat is 7.54.77.5 - 4.7?\newline7.54.7=2.87.5 - 4.7 = 2.8
  2. Subtract Coefficients: Write the answer in scientific notation.\newlineSince we subtracted the coefficients and the power of 1010 remains the same, we can write the result as:\newline2.8×1062.8 \times 10^6
  3. Write in Scientific Notation: Choose the equivalent expression for (7.5×106)(4.7×106)(7.5 \times 10^6) - (4.7 \times 10^6).\newlineThe correct answer is 2.8×1062.8 \times 10^6.
