Q. Multiply.\newline(3×101)(3×104)(3 \times 10^1)(3 \times 10^4)\newlineChoices:\newline(A) 9×1059 \times 10^5\newline(B) 9×1049 \times 10^4\newline(C) 9×1019 \times 10^1\newline(D) 9×1039 \times 10^3
  1. Identify Coefficients and Power Terms: We have: \newline(3×101)(3×104)(3 \times 10^1)(3 \times 10^4) \newlineGroup the coefficients and power terms together. \newlineCoefficients: 33 and 33 \newlinePower terms: 10110^1 and 10410^4
  2. Multiply Coefficients: What is 3×33 \times 3? Multiply the coefficients. \newline3×3=93 \times 3 = 9
  3. Combine Power Terms: Write 101×10410^1 \times 10^4 as a single power of 1010. When multiplying powers with the same base, we add the exponents. \newline101×10410^1 \times 10^4\newline= 10(1+4)10^{(1 + 4)}\newline= 10510^5
  4. Write Final Answer: We found: \newlineCoefficient = 99 \newlinePower term = 10510^5 \newlineWrite the final answer in scientific notation. Substitute 99 for aa and 55 for bb in a×10ba \times 10^b. \newlineScientific notation: 9×1059 \times 10^5
