To simplify the expression, first convert each number into standard form. Step 1: Express each number in standard form. 0.000215 = 2.15 × 10^-4 0.000028 = 2.8 × 10^-5 Step 2: Multiply the standard form expressions. (2.15 × 10^-4) × (2.8 × 10^-5) Step 3: Multiply the numerical parts and the powers of 10 separately. (2.15 × 2.8) × (10^-4 × 10^-5) Step 4: Perform the multiplication of the numerical parts. 2.15 × 2.8 = 6.02 Step 5: Perform the multiplication of the powers of 10 by adding the exponents. 10^-4 × 10^-5 = 10^(-4) + (-5) = 10^-9 Step 6: Combine the results to get the final answer in standard form. 6.02 × 10^-9 The simplified expression in standard form is 6.02 × 10^-9.
