Add. Write your answer in scientific notation. (5.84 * 10^2) + (2.85 * 10^2) Choices: (A)8.69 * 10^2 (B)8.69 * 10^4 (C)4.77 * 10^2 (D)4.77 * 10^4

Add Coefficients: We have the following numbers to add: (5.84 * 10^2) + (2.85 * 10^2) Since the powers of 10 are the same, we can directly add the coefficients. What is 5.84 + 2.85? 5.84 + 2.85 = 8.69Write in Scientific Notation: Write the answer in scientific notation. Since we have added the coefficients, we keep the power of 10 the same. Scientific notation: 8.69 * 10^2Find Equivalent Expression: Choose the equivalent expression for (5.84 * 10^2) + (2.85 * 10^2). (5.84 * 10^2) + (2.85 * 10^2) = 8.69 * 10^2
