Full solution

Q. Subtract. Write your answer in scientific notation.\newline(9.832×103)−(1.645×103)(9.832 \times 10^3) - (1.645 \times 10^3)\newlineChoices:\newline(A) 8.187×1038.187 \times 10^3\newline(B) 7.725×1037.725 \times 10^3\newline(C) 4.893×1034.893 \times 10^3\newline(D) 1.094×1031.094 \times 10^3
  1. Subtract coefficients, keep exponent: Subtract the coefficients of the given numbers while keeping the exponent the same since they are both powers of 10310^3. 9.832−1.645=8.1879.832 - 1.645 = 8.187
  2. Write final answer in scientific notation: Write the final answer in scientific notation. 8.187×1038.187 \times 10^3
  3. Choose correct equivalent expression: Choose the equivalent expression for the final answer from the given choices.\newlineThe correct choice is (A)8.187×103(A)8.187 \times 10^3.
