How do you evaluate scientific notation?

Answer 1

A number in scientific notation is written as a * 10b where 1 ≤ a < 10 (although a can be negative with the domain reversed) and b is an integer (negative or positive).

To convert a number in scientific notation to normal form:

· If b is positive, move the decimal point b places to the right in the number a - adding 0s at the end of the number, if required.

· If b is negative, move the decimal point b places to the left in the number a - adding leading 0s after the decimal point, if required.

For example:

4.56*105 = 456000.

4.56*10-5 = 0.0000456
