1) 27,854 × 10³ = 27 854
2) 0,0055 × 10⁴ = 55
3) -2,7 = -27 ×10⁻¹
4) 10⁻⁶ × 52 = 0,000 052
5) 10⁸ × 3 = 300 000 000
6) 0,00125 = 12,5 × 10⁻⁴
V]
A = (10⁵ × 10⁻² × 10⁴) / 10⁻³ × 10⁷
A = 10³
B = (10⁻⁵ × 10 × 10³) / 10² × 10⁻⁴
B = 10¹
VI]
C = (21 × 10⁸) / 14 × 10³
C = 1,5 × 10⁵
D = 4,8 × 10⁻3 / -6 × 10⁻⁵
D = -8 × 10¹
