Add. Write your answer in scientific notation. (5 * 10^3) + (1.7 * 10^3) Choices: (A)8.5 * 10^3 (B)6.7 * 10^6 (C)8.5 * 10^6 (D)6.7 * 10^3

Identify Coefficients and Powers: Identify the coefficients and the powers of 10 in both terms. We have (5 * 10^3) and (1.7 * 10^3). Both terms have the same power of 10, which is 10^3.Add Coefficients: Add the coefficients since the powers of 10 are the same. What is 5 + 1.7? 5 + 1.7 = 6.7Write in Scientific Notation: Write the answer in scientific notation. Since we have found the sum of the coefficients to be 6.7, we keep the power of 10 the same. Scientific notation: 6.7 * 10^3Choose Equivalent Expression: Choose the equivalent expression for (5 * 10^3) + (1.7 * 10^3). (5 * 10^3) + (1.7 * 10^3) = 6.7 * 10^3 (5 * 10^3) + (1.7 * 10^3) is equivalent to 6.7 * 10^3.
