Subtract. Write your answer in scientific notation. (9 * 10^5) - (7.7 * 10^5) Choices: (A)1.3 * 10^5 (B)1.3 * 10^0 (C)5.4 * 10^5 (D)5.4 * 10^0

Identify Subtraction Problem: We have the following subtraction problem: (9 * 10^5) - (7.7 * 10^5) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 9 - 7.7? 9 - 7.7 = 1.3Perform Subtraction: Write the answer in scientific notation. Since we have subtracted the coefficients, we keep the power of 10 the same. Scientific notation: 1.3 * 10^5Write in Scientific Notation: Choose the equivalent expression for (9 * 10^5) - (7.7 * 10^5). (9 * 10^5) - (7.7 * 10^5) = 1.3 * 10^5 The correct choice is (A) 1.3 * 10^5.
