2,430,000 in scientific notation is 2.43 × 106
The scientific notation of 4.2ns is 4.2 × 100ns
200.1 in scientific notation is: 2.001 × 102
13,500 in scientific notation is 1.35 × 104
It is 7.8*10^5 in scientific notation
You have it in reverse. Scientific notation is useful for measuring stars.
Scientific notation is useful in economics to compute very large or very small numbers.
Scientific notation is useful in mathematics because it makes very large or very small numbers easier to compute.
You use scientific notation when it comes to "too large" or "too small" numbers. The reasons why using scientific notation is useful are that it saves time to do the computation and also that it makes people's life easier to compute values instead of writing them out completely!
Scientific notation gives a compact notation, which is especially useful for writing down - and doing calculations with - very large, and very small, numbers.
When you have a number with a large amount of digits.
Scientific notation tends to be useful any time you have to deal with either very large numbers or very small numbers.
1.9 X 1027 kilograms ------------------------ This is the mass of Jupiter. Try writing that out in longhand and you will see why scientific notation is useful to astronomers. Very large numbers in astronomy need a way to write them in a useful and compact form.
When numbers are tremendously large or small.
Scientific notation
It is used for recording very large or very small numbers. This is particularly true for sciences.
Since the numbers astronomers use are often very large or very small, they frequently use scientific notation to describe sizes and sentences in the universe.
