Scientific Notation
Scientific notation is the expression of a number based on the largest exponent of 10 for its value, where the form is a decimal number A x 10n.

What is 0.0000086 in scientific notation?
It is 8.6*10-6.
It is 8.6*10-6.
It is 8.6*10-6.
It is 8.6*10-6.
What is the definition of exponential notation?
This means multiply the base times itself as many times as the exponents says.
Ex: 4 x 4 x 4 =64
4 to the power of 3 = 64
What are some of the rules of scientific notation?
The first number must be a nonzero single-digit integer.
The exponent must be an integer.
What is 108000000 in scientific notation?
108,000,000 in scientific notation is 1.08 x 10^8 or 1.08E8
What is the purpose of a scientific notation?
To write out very large or very small numbers using a minimum amount of digits
For example 1,000,000 = 1.0*106 and 0.000001 = 1.0*10-6 in scientific notation.
What is the general format of the scientific notation?
The general form of a number in scientific notation is
a x 10b, where b is an integer, and 1 <= a < 10.
Scientific notation is a convinient way of writing numbers that are either very big, or very small (close to zero).
If you have a power of 10, like 100,000, you can write it as 105.
If you have another number, that is not a power of 10, for example 200,000, you can write it as 2 x 105, whereas 250,000 would be 2.5 x 105.
In general, a number in scientific notation is any number, multiplied by a power of 10. In standard form, this "any number" will be a number between 1 and 10 (excluding 10), but it doesn't need be written this way. A power of 1000 is sometimes easier to read. For example, 28 x 109 is clearly 28 billion. (The standard notation would be 2.8 x 1010.)
Express 2 750 389 in sientific notation?
It is 2.750389*10^6 although if you retain all the digits after the decimal point, it is hardly worth the effort.
