How do you change a number from scientific notation?

Answer 1

Scientific notation is a way of representing numbers in the form

a*10b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive).

a is called the mantissa and b is called the exponent.

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 0s immediately after the decimal point, if required.

For example:

4.56*105 = 456000.

4.56*10-5 = 0.0000456
