Add. Write your answer in scientific notation. (5.059 * 10^4) + (2.7 * 10^4) Choices: (A)5.086 * 10^4 (B)7.759 * 10^8 (C)5.086 * 10^8 (D)7.759 * 10^4

Add Coefficients: Add the coefficients of the given numbers. 5.059 + 2.7 = 7.759Combine Exponents: Since the exponents of 10 are the same (10^4), we can directly add the coefficients and keep the exponent unchanged. The sum in scientific notation is 7.759 * 10^4.Choose Correct Answer: Choose the equivalent expression for the final answer from the given choices. The correct choice is (D) 7.759 * 10^4.
