Subtract. Write your answer in scientific notation. (9.94 * 10^7) - (5.2 * 10^7) Choices: (A)4.74 * 10^7 (B)4.74 * 10^9 (C)4.74 * 10^8 (D)4.74 * 10^10

Calculate Coefficients: We have: (9.94 * 10^7) - (5.2 * 10^7) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 9.94 - 5.2? 9.94 - 5.2 = 4.74Convert to Scientific Notation: Write the answer in scientific notation. Since we subtracted the coefficients and the power of 10 remains the same, we keep the power of 10 as is. Scientific notation: 4.74 * 10^7Find Equivalent Expression: Choose the equivalent expression for (9.94 * 10^7) - (5.2 * 10^7). (9.94 * 10^7) - (5.2 * 10^7) = 4.74 * 10^7 (9.94 * 10^7) - (5.2 * 10^7) is equivalent to 4.74 * 10^7.
