Q. Simplify. Your answer should be in proper scientific notation:\newline(2×103)(4×105)(8×103) \left(2 \times 10^{3}\right)\left(4 \times 10^{5}\right)\left(8 \times 10^{3}\right)
  1. Multiply Coefficients: Multiply the coefficients (22, 44, and 88) together.\newlineCalculation: 2×4×8=642 \times 4 \times 8 = 64\newlineMath error check:
  2. Add Exponents: Add the exponents of 1010 (33, 55, and 33) together since we are multiplying powers of the same base.\newlineCalculation: 3+5+3=113 + 5 + 3 = 11\newlineMath error check:
  3. Combine Results: Combine the results from Step 11 and Step 22 to form a single expression in scientific notation.\newlineCalculation: 64×101164 \times 10^{11}\newlineMath error check:
  4. Adjust Coefficient: Adjust the coefficient to be between 11 and 1010 for proper scientific notation. Since 6464 is not between 11 and 1010, we need to express it as 6.4×1016.4 \times 10^{1}.\newlineCalculation: 64=6.4×10164 = 6.4 \times 10^{1}\newlineMath error check:
  5. Final Answer: Combine the result from Step 44 with the exponent from Step 33 to get the final answer in proper scientific notation.\newlineCalculation: 6.4×101×1011=6.4×101+11=6.4×10126.4 \times 10^{1} \times 10^{11} = 6.4 \times 10^{1+11} = 6.4 \times 10^{12}\newlineMath error check:
