Scientific Notation is another form of writing a large number (actually..any number)

The first number must be less than 10, while the second number has to be 10 to any power.


21.9 in scientific notation would be...... 2.19 X 10^1


**10^1 = 10...

2.19 X 10 = 21.9

the first number is less than ten

the second number is ten to the first degree
