Scientific notation is a way of representing numbers, usually very large or very small, in the form
a*10b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive).
a is called the mantissa and b is called the exponent.
To convert a number to scientific notation:
· If the number has no decimal point, then add one at the end.
· Then move the decimal point to just after the first digit while counting the number of places you have moved it.
· The new number, formed after moving the decimal point is a.
· The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
For example:
23045.06 becomes 2.304506*104
0.00023004 becomes 2.3004*10-4
Such numbers would not need to be written in scientific notation but if need be it is: 1.2345*10^2
Yes - you can always convert numbers to scientific notation - whether they're whole numbers, or decimals.
Ordinary notation is where the numbers are laid, or written out. Scientific notation is a short handed version with numbers that indicate the amount of zeroes behind the end of the numbers.
Such numbers usually are not written in scientific notation but just for the exercise it is:- 1.095*102
0.000729512 in scientific notation written to 3 significant places is 7.30x10-4.
Here are the quick examples of the numbers written in scientific notation: 3.4 = 3.4 x 100 34.0 = 3.4 x 10
Usually numbers under 1000 are not written in scientific notation however 226 would be written as 2.26 x 102.
As far as it is possible to tell, neither of the two are in scientific notation.
When they are very large or very small.
Scientific notation is a way of writing numbers that are too big or too small to be conveniently written in decimal form. In normalized scientific notation all numbers are written in the form a x 10^b (a times ten raised to the power of b) where a is a nonzero single-digit integer and b is an integer.
Scientific notation is a way that scientists are able to handle either very large numbers or vary small numbers. The scientific notation for the number 70,680,000 would be written as 7.068 x 10^7.
so they are smaller quicker and easier to write
