Q. Subtract. Write your answer in scientific notation.\newline(7.15×105)−(5.964×105)(7.15 \times 10^5) - (5.964 \times 10^5)\newlineChoices:\newline(A) 1.186×1071.186 \times 10^7\newline(B) 1.186×1061.186 \times 10^6\newline(C) 1.186×1051.186 \times 10^5\newline(D) 1.186×1041.186 \times 10^4
  1. Subtract coefficients, keep exponent: Subtract the coefficients of the given numbers while keeping the exponent the same since they are like terms. 7.15−5.964=1.1867.15 - 5.964 = 1.186
  2. Write final answer in scientific notation: Write the final answer in scientific notation using the common exponent from the original terms. 1.186×1051.186 \times 10^5
  3. Choose equivalent expression: Choose the equivalent expression for the final answer from the given choices.\newlineThe correct choice is (C)1.186×105(C)1.186 \times 10^5
