Q. Subtract. Write your answer in scientific notation.\newline(5.6×106)(1.1×106)(5.6 \times 10^6) - (1.1 \times 10^6)\newlineChoices:\newline(A) 6.16×1056.16 \times 10^5\newline(B) 4.5×1054.5 \times 10^5\newline(C) 4.5×1064.5 \times 10^6\newline(D) 6.16×1066.16 \times 10^6
  1. Identify Coefficients: We have:\newline(5.6×106)(1.1×106)(5.6 \times 10^6) - (1.1 \times 10^6)\newlineSince the powers of 1010 are the same, we can subtract the coefficients directly.\newlineWhat is 5.61.15.6 - 1.1?\newline5.61.1=4.55.6 - 1.1 = 4.5
  2. Convert to Scientific Notation: Write the answer in scientific notation.\newlineSubstitute 4.54.5 for the coefficient and 66 for the exponent in a×10ba \times 10^b.\newlineScientific notation: 4.5×1064.5 \times 10^6
  3. Find Equivalent Expression: Choose the equivalent expression for (5.6×106)(1.1×106)(5.6 \times 10^6) - (1.1 \times 10^6).(5.6×106)(1.1×106)=4.5×106(5.6 \times 10^6) - (1.1 \times 10^6) = 4.5 \times 10^6(5.6×106)(1.1×106)(5.6 \times 10^6) - (1.1 \times 10^6) is equivalent to 4.5×1064.5 \times 10^6.
