Q. 11.) (7.3×108)(2.4×103) \left(7.3 \times 10^{8}\right)\left(2.4 \times 10^{3}\right)
  1. Multiply non-exponential parts: First, multiply the non-exponential parts: 7.37.3 times 2.42.4.\newlineCalculation: 7.3×2.4=17.527.3 \times 2.4 = 17.52
  2. Add exponents of 1010: Next, add the exponents of 1010 because when multiplying powers with the same base, you add the exponents.\newlineCalculation: 108+3=101110^{8 + 3} = 10^{11}
  3. Combine results for final answer: Now, combine the two results to get the final answer.\newlineCalculation: 17.52×101117.52 \times 10^{11}
  4. Correct multiplication error: Oops, I just realized I made a mistake in the second step. The correct multiplication of 7.37.3 and 2.42.4 is not 17.5217.52.
