Q. Find the difference. Write your answer in scientific\newline(2.4×10−1)−(5.5×10−2)= \left(2.4 \times 10^{-1}\right)-\left(5.5 \times 10^{-2}\right)=
  1. Align Exponents: First, align the exponents so we can subtract the numbers. 2.4×10−12.4 \times 10^{-1} is the same as 24×10−224 \times 10^{-2}.
  2. Subtract Numbers: Now subtract the numbers with the same exponent.\newline(24×10−2)−(5.5×10−2)=(24−5.5)×10−2(24 \times 10^{-2}) - (5.5 \times 10^{-2}) = (24 - 5.5) \times 10^{-2}.
  3. Perform Subtraction: Do the subtraction. 24−5.5=18.524 - 5.5 = 18.5.
  4. Write in Scientific Notation: Write the result in scientific notation.\newline18.5×10−218.5 \times 10^{-2} is the same as 1.85×10−11.85 \times 10^{-1}.
