Which shows the correct way to use expanded form to multiply 38,070 × 100?

(30,000 + 8,000 + 70) × 100 = 3,000,000 + 800,000 + 7,000
(30,000 + 8,000 + 700) × 100 = 3,000,000 + 800,000 + 7,000
(30,000 + 8,000 + 70) × 100 = 30,000,000 + 8,000,000 + 70,000
(30,000 + 8,000 + 700) × 100 = 30,000,000 + 8,000,000 + 70,000
