Scientific Notation
SCIENTIFIC NOTATION a
Scientific notation for a number is an expression of the type
where n is an integer, M is greater than or equal to 1 and less than 10 and M is expressed in decimal notation.

Scientific Notation a
Convert between scientific notation and decimal notation.
Converting from scientific notation to decimal notation involves multiplying by a power of 10. To convert to decimal notation, we move the decimal point.

Scientific Notation a
Convert between scientific notation and decimal notation.
We reverse the process when converting from decimal notation to scientific notation. To convert a number to scientific notation, we write it in the form where M looks like the original number but with exactly one nonzero digit to the immediate left of the decimal point.
