Q. Subtract. Write your answer in scientific notation.\newline(9.04×109)−(5.86×109)(9.04 \times 10^9) - (5.86 \times 10^9)\newlineChoices:\newline(A) 9.423×1099.423 \times 10^9\newline(B) 3.18×1093.18 \times 10^9\newline(C) 5.17×1095.17 \times 10^9\newline(D) 4×1094 \times 10^9
  1. Subtract Coefficients, Keep Exponent: Subtract the coefficients of the given numbers while keeping the exponent the same since they are like terms. 9.04−5.86=3.189.04 - 5.86 = 3.18
  2. Write in Scientific Notation: Write the final answer in scientific notation using the common exponent. 3.18×1093.18 \times 10^9
  3. Choose Equivalent Expression: Choose the equivalent expression for the final answer from the given choices.\newlineThe correct choice is (B)3.18×109(B) 3.18 \times 10^9.
