Q. Subtract. Write your answer in scientific notation.\newline(8.97×102)−(5×102)(8.97 \times 10^2) - (5 \times 10^2)\newlineChoices:\newline(A) 3.97×1023.97 \times 10^2\newline(B) 8.4×108.4 \times 10\newline(C) 3.97×1003.97 \times 10^0\newline(D) 8.4×1038.4 \times 10^3
  1. Subtraction Problem: We have the following subtraction problem in scientific notation:\newline(8.97×102)−(5×102)(8.97 \times 10^2) - (5 \times 10^2)\newlineSince the powers of 1010 are the same, we can directly subtract the coefficients.\newlineWhat is 8.97−58.97 - 5?\newline8.97−5=3.978.97 - 5 = 3.97
  2. Subtract Coefficients: Write the answer in scientific notation.\newlineSince we subtracted the coefficients and the power of 1010 remains the same, we have:\newline3.97×1023.97 \times 10^2
  3. Write in Scientific Notation: Choose the equivalent expression for (8.97×102)−(5×102)(8.97 \times 10^2) - (5 \times 10^2).(8.97×102)−(5×102)=3.97×102(8.97 \times 10^2) - (5 \times 10^2) = 3.97 \times 10^2 The correct choice is (A)3.97×102(A)3.97 \times 10^2.
