Q. Multiply.\newline(2×101)(3×102)(2 \times 10^1)(3 \times 10^2)\newlineChoices:\newline(A) 6×1096 \times 10^9\newline(B) 6×1036 \times 10^3\newline(C) 6×1086 \times 10^8\newline(D) 6×1056 \times 10^5
  1. Identify Coefficients and Power Terms: We have: \newline(2×101)(3×102)(2 \times 10^1)(3 \times 10^2) \newlineGroup the coefficients and power terms together. \newlineCoefficients: 22 and 33 \newlinePower terms: 10110^1 and 10210^2
  2. Multiply Coefficients: What is 2×32 \times 3? Multiply the coefficients. \newline2×3=62 \times 3 = 6
  3. Combine Power Terms: Write 101×10210^1 \times 10^2 as a single power of 1010. When multiplying powers with the same base, we add the exponents. \newline101×10210^1 \times 10^2\newline=10(1+2)= 10^{(1 + 2)}\newline=103= 10^3
  4. Write Final Answer in Scientific Notation: We found: \newlineCoefficient = 66 \newlinePower term = 10310^3 \newlineWrite the final answer in scientific notation. Substitute 66 for aa and 33 for bb in a×10ba \times 10^b. \newlineScientific notation: 6×1036 \times 10^3
