What is Scientfic Notation?

How Scientifc Notation is used in Astronomy?

Scientific notation is a way to express very large and very small numbers.

When the exponent is a negative number it means the decimal is going to the right.

When the exponent is a postive number it means the decimal is going to the left.

What is the standard form of 1.989×1033?

To simplify big numbers to be easier to divide, multiply, add, and subract. To make the cofficient easier to say, read, and write

(4.215 x 10-2) + (3.2 x 10-4) = 4.247 x 10-2

(3.4 x 106)(4.2 x 103) = 1.4 x 1010

(3.2 x 103)/(5.7 x 10-2) = 5.6 x 104
