New moon is the phase in which it cannot be seen
Answer:
6.32 × 10⁻³
3.2560008× 10⁷
5.630× 10⁰
9.5002× 10¹
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.00632
In scientific notation = 6.32 × 10⁻³
32,560,008
In scientific notation = 3.2560008× 10⁷
5.630
In scientific notation = 5.630× 10⁰
95.002
In scientific notation = 9.5002× 10¹
