Add. Write your answer in scientific notation. (4.7 * 10^3) + (3 * 10^3) Choices: (A)7.7 * 10^6 (B)7.7 * 10^3 (C)5 * 10^3 (D)5 * 10^6

Add Coefficients: We have the following expression to add: (4.7 * 10^3) + (3 * 10^3) Since the powers of 10 are the same, we can directly add the coefficients. What is 4.7 + 3? 4.7 + 3 = 7.7Convert to Scientific Notation: Write the answer in scientific notation. We keep the power of 10 the same and use the sum of the coefficients from Step 1. Scientific notation: 7.7 * 10^3Choose Equivalent Expression: Choose the equivalent expression for (4.7 * 10^3) + (3 * 10^3). (4.7 * 10^3) + (3 * 10^3) = 7.7 * 10^3 The correct choice is (B) 7.7 * 10^3.
