a). (5 x 10²) x (3 x 10²)
Jawaban:
(5 x 10²) x (3 x 10²)
= (5 x 3) x (10² x 10²)
= 15 x 10²⁺²
= 15 x 10⁴
= 1,5 x 10⁵
b). (7,2 x 10⁻¹³) x (4 x 10⁵)
Jawaban:
(7,2 x 10⁻¹³) x (4 x 10⁵)
= (7,2 x 4) x (10⁻¹³ x 10⁵)
= 28,8 x 10⁻¹³⁺⁵
= 28,8 x 10⁻⁸
= 2,88 x 10⁻⁷
c). (5,25 x 10⁶ ) x (10⁻¹²)
Jawaban:
(5,25 x 10⁶ ) x (10⁻¹²)
= 5,25 x 10⁶ x 10⁻¹²
= 5,25 x 10⁶⁻¹²
= 5,25 x 10⁻⁶
