What Is Scientific Notaion?

Question

can you please tell me what it is? and can you give me a example?

Answer 1

Scientific Notation is a way of expressing numbers. For Example the number 5256. In Scientific Notation that number is 5.256 X 10^1, always keep 1 digit in front of the decimal and two or three after it. the number .0876 would be expressed as 8.76 X 10^-2

Answer 2

This explains it better than I could, and it gives examples.

(Wow, that guy below just copied and pasted this same wikipedia article and didn't give credit.)

Answer 3

Scientific notation is something to do with numbers.  If you square a number (by putting a little 2 right at the top right of the number) you are using scientific notation.  To square a number means to multiply the number by itself.  To cube a number, (to put a little 3 at the top right) means to multiply the number by itself 3 times.  From there they call it powers.  Say, 5 to the power of 6 would mean 5 with a little 6 at the top right corner.  That means to multiply 5 by itself 6 times.  For more information, check out this link.  http://en.wikipedia.org/wiki/Scientific_...

Answer 4

Scientific notation is a way to give measurements that are huge in size. For example, say that the moon is 12,000,000,000 miles away from earth (just a hypothetical situation). Then in scientific notation it would be 1.2 x 10 to the 10th power. Or, if an atom is 16,000,000 mm smaller than a grape than it would be 1.6 x 10 to the negative 7th power. So instead of writing all the extra "zeros" or numbers, they make into an equation.

Answer 5

A shorthand way of writing very large or very small numbers. A number expressed in scientific notation is expressed as a decimal number between 1 ...

Answer 6

Scientific notation, also sometimes known as standard form or as exponential notation, is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation. Scientific notation has a number of useful properties and is often favoured by scientists, mathematicians and engineers, who work with such numbers.

In scientific notation, numbers are written in the form:



("a times ten to the power of b"), where the exponent b is an integer, and the coefficient a is any real number, called the significand or mantissa (though the term "mantissa" may cause confusion as it can also refer to the fractional part of the common logarithm). If the number is negative then a minus sign precedes the first of the decimal digits of a (as in ordinary decimal notation). For example:

Ordinary decimal notation Scientific notation

1                                                          1×10^0

30                                                        3×10^1

5 720 000 000                                   5.72×10^9

−0.000 000 006 1                            ÃƒÂ¢Ã‚ˆÂ’6.1×10^(−9 )
