Here are the solutions to your homework problems. 1. Write the number in expanded form. a) 1.24 × 10^3 Step 1: Identify the exponent. The exponent is 3. Step 2: Move the decimal point 3 places to the right. 1.24 × 10^3 = 1240 The expanded form is 1240. b) 9.2014 × 10^4 Step 1: Identify the exponent. The exponent is 4. Step 2: Move the decimal point 4 places to the right. 9.2014 × 10^4 = 92014 The expanded form is 92014. 2. Write the number in scientific notation. a) 21900000 Step 1: Place the decimal point after the first non-zero digit. 2.1900000 Step 2: Count the number of places the decimal point moved from its original position (at the end of the number). It moved 7 places to the left. 21900000 = 2.19 × 10^7 The scientific notation is 2.19 × 10^7. b) 367000000000 Step 1: Place the decimal point after the first non-zero digit. 3.67000000000 Step 2: Count the number of places the decimal point moved from its original position (at the end of the number). It moved 11 places to the left. 367000000000 = 3.67 × 10^11 The scientific notation is 3.67 × 10^11. Send me the next one 📸
