AB = 8 x 10 ⁷ x 2 x 10 ³
= 16 x 10 ¹⁰ = 1.6 x 10 ⁷
A/B = 8 x 10⁷ : 2 x 10 ³ = 4 x 10 ⁴
AB = 7.5 x 10⁴ x 1.5 x 10 ⁻⁵
= 11.25 x 10 ⁻¹
= 1.125 x 10 ³ x 10 ⁻¹ = 1.125 x 10²
A/B = 7.5 x 10 ⁴ : 1.5 x 10 ⁻⁵ = 5 x 10 ⁹
AB = 1.56 x 10 ⁻⁸ x - 1.2 x 10 ⁻⁴
= - 1.872 x 10 ⁻¹²
A/B = 1.56 x 10 ⁻⁸ : - 1.2 x 10 ⁻⁴
= - 1.3 x 10 ⁻⁴
