Transcript Scientific Notation - Exponents

Scientific Notation
When using Scientific Notation, there are
two kinds of exponents: positive and
negative
2.35 x 10
3.97 x 10
When changing scientific notation to
standard notation, the exponent tells you
if you should move the decimal:
4.08 x 103 = 4 0 8
Don’t forget to fill in your zeroes!
When changing scientific notation to
standard notation, the exponent tells you
if you should move the decimal:
4.08 x 10-3 =
408
Don’t forget to fill in your zeroes!
An easy way to remember this is:
The exponent also tells how many spaces
to move the decimal:
4.08 x 10
=
408
