Sagot :
D = (49 × 10³⁵) / (7 × 10³⁴)
= 49/7 × 10³⁵⁻³⁴
= 7 × 10¹
= 70
= 7 × 10¹
E = (150 × 10³ × 8 × 10⁵) / (6 × 10⁷)
= (150 × 8) / (3 × 2) × 10³⁺⁵⁻⁷
= 50 × 4 × 10¹
= 2000
= 2 × 10³
F = (14 × 10² × 75 × 10⁻⁷) / (35 × 10⁻³)
= (14 × 75) / (7 × 5) × 10²⁻⁷⁺³
= 2 × 15 × 10⁻²
= 0,3
= 3 × 10⁻¹
G = (35 × 10¹⁸ × 3 × 10⁻⁵) / (42 × 10¹⁰)
= (35 × 3) / (7 × 3 × 2) × 10¹⁸⁻⁵⁻¹⁰
= 5 / 2 × 10³
= 2500
= 2,5 × 10³
H = (1,6 × (10⁻³)⁴) / (4 × 10⁻⁹)
= 1,6/4 × 10⁻¹²⁺⁹
= 0,4 × 10⁻³
= 0,0004
= 4 × 10⁻⁴
I = (3,9 × (10⁻²)²) / (3 × 10⁻⁵)
= 3,9/3 × 10⁻⁴⁺⁵
= 1,3 × 10¹
= 13
= 1,3 × 10¹
J = (2 × 10⁷ × 5 × (10⁻⁵)²) / (2 + 18)
= 10/20 × 10⁷⁻¹⁰
= 0,5 × 10⁻³
= 0,0005
= 5 × 10⁻⁴
