Which equation shows how to find the product of 100,000 and 1,000,000 using scientific notation?
a) 100,000 × 1,000,000 = (1 × 105) × (1 × 106) = 1 × 10(5 + 6) = 1 × 1011
b) 100,000 × 1,000,000 = (1 × 105) × (1 × 106) = 1 × 10(5 × 6) = 1 × 1030
c) 100,000 × 1,000,000 = (1 × 106) × (1 × 107) = 1 × 10(6 + 7) = 1 × 1013
d) 100,000 × 1,000,000 = (1 × 106) × (1 × 107) = 1 × 10(6 × 7) = 1 × 1042
