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.
Which answer choice below is the product of (2.58 107)(3.6 10-2) written in scientific notation?
If you mean: (2.58*10^7) times (3.6*10^-2) then it is 9.288*10^5 = 928800
How do you write 75000000 in scientific notation?
75000000 can be written as 7.50 x 10^7 in scientific notation.
What is the proper name for the coefficient of a number written in scientific notation?
The significand. Some people call it the mantissa.
