Answer:
<em>a= In scientific notation</em>
6.96×10⁵ Km
<em>b =In expanded notation</em>
0.00019 mm
Explanation:
Given data:
Radius of sun = 696000 Km
size of bacterial cell = 1.9 ×10⁻⁴ mm
Radius of sun in scientific notation = ?
Size of bacterial cell in expanded notation = ?
Solution:
Radius of sun:
696000 Km
<em>In scientific notation</em>
6.96×10⁵ Km
Size of bacterial cell:
1.9 ×10⁻⁴ mm
<em>In expanded notation</em>
1.9/ 10000 = 0.00019 mm
