Add. Write your answer in scientific notation. (1.9 * 10^8) + (3.4 * 10^8) Choices: (A)5.3 * 10^8 (B)6.46 * 10^8 (C)6.46 * 10^7 (D)5.3 * 10^7

Identify Expression: We have the following expression to add: (1.9 * 10^8) + (3.4 * 10^8) Since the powers of 10 are the same, we can directly add the coefficients. What is 1.9 + 3.4? 1.9 + 3.4 = 5.3Add Coefficients: Write the answer in scientific notation. Since we have found the sum of the coefficients to be 5.3, we keep the power of 10 the same. Scientific notation: 5.3 * 10^8Convert to Scientific Notation: Choose the equivalent expression for (1.9 * 10^8) + (3.4 * 10^8). (1.9 * 10^8) + (3.4 * 10^8) = 5.3 * 10^8 The correct choice is (A) 5.3 * 10^8.
