Q. Subtract. Write your answer in scientific notation.\newline(8.3×108)(4.6×108)(8.3 \times 10^8) - (4.6 \times 10^8)\newlineChoices:\newline(A) 3.7×1083.7 \times 10^8\newline(B) 3.8×1083.8 \times 10^8\newline(C) 3.8×1073.8 \times 10^7\newline(D) 3.7×1073.7 \times 10^7
  1. Given Expression: We have:\newline(8.3×108)(4.6×108)(8.3 \times 10^8) - (4.6 \times 10^8)\newlineSince the powers of 1010 are the same, we can subtract the coefficients directly.\newlineWhat is 8.34.68.3 - 4.6?\newline8.34.6=3.78.3 - 4.6 = 3.7
  2. Subtraction and Coefficients: Write the answer in scientific notation.\newlineSubstitute 3.73.7 for the coefficient and 88 for the exponent in a×10ba \times 10^b.\newlineScientific notation: 3.7×1083.7 \times 10^8
  3. Scientific Notation: Choose the equivalent expression for (8.3×108)(4.6×108)(8.3 \times 10^8) - (4.6 \times 10^8).(8.3×108)(4.6×108)=3.7×108(8.3 \times 10^8) - (4.6 \times 10^8) = 3.7 \times 10^8(8.3×108)(4.6×108)(8.3 \times 10^8) - (4.6 \times 10^8) is equivalent to 3.7×1083.7 \times 10^8.
