Answer 1

Answer:

When using the scientific notation system to express large numbers, move the decimal point until one digit(s) remain(s) to the left, then indicate the number of moves of the decimal point as the power of ten.

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 the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

Radius of sun:

696000 Km

In scientific notation

6.96000 × 10⁵ Km

The expanded notation is standard notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.
