Question

Choose the letters of ALL of the numbers that are in proper scientific notation: A)  15 ×10^(3) B)  2.3 ×10^(8) C)  0.6 ×10^(2) D)  8+10^(4) E)  7.2 ×6^(5)

Review definition scientific notation: Review the definition of proper scientific notation. Proper scientific notation requires a number to be expressed as a product of a number between 1 and 10 and a power of 10. The coefficient (the number between 1 and 10) must have only one non-zero digit to the left of the decimal point.Evaluate option A: Evaluate option A (15 × 10^3). The coefficient is 15, which is not between 1 and 10. Therefore, this is not in proper scientific notation.Evaluate option B: Evaluate option B (2.3 × 10^8). The coefficient is 2.3, which is between 1 and 10, and there is only one non-zero digit to the left of the decimal point. This is in proper scientific notation.Evaluate option C: Evaluate option C (0.6 × 10^2). The coefficient is 0.6, which is between 1 and 10, and there is only one non-zero digit to the left of the decimal point. This is in proper scientific notation.Evaluate option D: Evaluate option D (8 + 10^4). This is not a product of a number and a power of 10; it is a sum. Therefore, this is not in proper scientific notation.Evaluate option E: Evaluate option E (7.2 × 6^5). This is a product of a number and a power of 6, not a power of 10. Therefore, this is not in proper scientific notation.
