Question and answer
Q: what are the practical usages of scientific notation?
A: 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 104 24327 = 2.4327 x
104 1000 = 1 x 103 7354 = 7.354 x 103 100 = 1 x 102 482 = 4.82 x 102 10 = 1 x 101 89 = 8.9 x 101 (not usually done) 1 = 100 1/10 = 0.1 = 1 x 10-1 0.32 = 3.2 x 10-1 (not usually done) 1/100 = 0.01 = 1 x 10-2 0.053 = 5.3 x 10-2 1/1000 = 0.001 = 1 x 10-3 0.0078 = 7.8 x 10-3 1/10000 = 0.0001 = 1 x 10-4 0.00044 = 4.4 x 10-4 ] ]
