Add. Write your answer in scientific notation. (1.53 * 10^4) + (8.17 * 10^4) Choices: (A)3.08 * 10^4 (B)9.7 * 10^8 (C)3.08 * 10^8 (D)9.7 * 10^4

Add Coefficients: We have the following expression to add: (1.53 * 10^4) + (8.17 * 10^4) Since the powers of 10 are the same, we can directly add the coefficients. What is 1.53 + 8.17? 1.53 + 8.17 = 9.70Convert to Scientific Notation: Write the answer in scientific notation. Substitute 9.70 for the coefficient and keep the power of 10 the same, which is 4. Scientific notation: 9.70 * 10^4Choose Correct Expression: Choose the equivalent expression for the sum of (1.53 * 10^4) and (8.17 * 10^4). (1.53 * 10^4) + (8.17 * 10^4) = 9.70 * 10^4 The correct choice is (D) 9.70 * 10^4.
