Add. Write your answer in scientific notation. (1.41 * 10^6) + (5.9 * 10^6) Choices: (A)8.319 * 10^7 (B)7.31 * 10^7 (C)8.319 * 10^6 (D)7.31 * 10^6

Addition Process: We have the following numbers to add: (1.41 * 10^6) + (5.9 * 10^6) Since the exponents of 10 are the same, we can directly add the coefficients (1.41 and 5.9). Let's perform the addition: 1.41 + 5.9 = 7.31Scientific Notation: Now that we have the sum of the coefficients, we can write the answer in scientific notation. The sum of the coefficients is 7.31, and since the exponent for both terms was 6, the exponent remains the same. Scientific notation: 7.31 * 10^6Equivalent Expression: Choose the equivalent expression for (1.41 * 10^6) + (5.9 * 10^6). (1.41 * 10^6) + (5.9 * 10^6) = 7.31 * 10^6 The correct answer is (D) 7.31 * 10^6.
