Answer:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation.
10000 = 1 x 10424327 = 2.4327 x 1041000 = 1 x 1037354 = 7.354 x 103100 = 1 x 102482 = 4.82 x 10210 = 1 x 10189 = 8.9 x 101 (not usually done)1 = 1001/10 = 0.1 = 1 x 10-10.32 = 3.2 x 10-1 (not usually done)1/100 = 0.01 = 1 x 10-20.053 = 5.3 x 10-21/1000 = 0.001 = 1 x 10-30.0078 = 7.8 x 10-31/10000 = 0.0001 = 1 x 10-40.00044 = 4.4 x 10-4
As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form. A positive exponent shows that the decimal point is shifted that number of places to the right.
