To express 2.5 in standard form (scientific notation), we need to write it as a number between 1 and 10 multiplied by a power of 10. Step 1: Identify the number. The number is 2.5. Step 2: Adjust the decimal point to get a number between 1 and 10. In this case, 2.5 is already between 1 and 10. Step 3: Determine the power of 10. Since the decimal point did not need to move, the power of 10 is 0 (10⁰ = 1). Step 4: Write the number in standard form. This is 2.5 × 10⁰. The standard form of 2.5 is 2.5 × 10⁰.
