Add. Write your answer in scientific notation. (3.955 * 10^3) + (2.473 * 10^3) Choices: (A)9.781 * 10^3 (B)6.428 * 10^3 (C)6.428 * 10^6 (D)9.781 * 10^6

Add Coefficients: Add the coefficients of the given numbers. 3.955 + 2.473 = 6.428Add in Scientific Notation: Since the exponents of 10 are the same, we can directly add the coefficients and keep the exponent unchanged. The sum in scientific notation is 6.428 × 10^3.Choose Correct Expression: Choose the equivalent expression for the final answer from the given choices. The correct choice is (B) 6.428 * 10^3.
