Q. Subtract. Write your answer in scientific notation.\newline(9.75×109)−(2.69×109)(9.75 \times 10^9) - (2.69 \times 10^9)\newlineChoices:\newline(A) 7.06×1067.06 \times 10^6\newline(B) 7.06×1097.06 \times 10^9\newline(C) 7.06×1087.06 \times 10^8\newline(D) 7.06×1077.06 \times 10^7
  1. Subtraction Problem: We have the following subtraction problem in scientific notation:\newline(9.75×109)−(2.69×109)(9.75 \times 10^9) - (2.69 \times 10^9)\newlineSince the powers of 1010 are the same, we can directly subtract the coefficients.\newlineWhat is 9.75−2.699.75 - 2.69?\newline9.75−2.69=7.069.75 - 2.69 = 7.06
  2. Subtract Coefficients: Write the answer in scientific notation.\newlineSince we subtracted the coefficients, the power of 1010 remains the same.\newlineScientific notation: 7.06×1097.06 \times 10^9
  3. Write in Scientific Notation: Choose the equivalent expression for (9.75×109)−(2.69×109)(9.75 \times 10^9) - (2.69 \times 10^9).(9.75×109)−(2.69×109)=7.06×109(9.75 \times 10^9) - (2.69 \times 10^9) = 7.06 \times 10^9The correct choice is (B) 7.06×1097.06 \times 10^9.
