Every whole number be written as a decimal; e.g 2 can be written as 2.00
Scientific notation consists of a number from 1-10, with the multiplication of 10 to the power of (x) for every spot that it takes for the decimal point to make the number 1-10. So to answer your question, 0.00120 in scientific notation would be 1.2 x1000. This is because the decimal point needed to be moved 3 spaces. So 10 times (x), in this 3, creates the formula 10 to the 3rd power. OR just write the number '1' down, and for every spot moved, add a 0. This is much easier (and not to mention FASTER) in my opinion.
Scientific notation uses short-hand for long numbers, writing the numbers in a standard form of a decimal number greater or equal to 1 and less than 10 multiplied by a power of 10, whereas ordinary notation just writes the number as one would every number. It helps to avoid errors when there could be a lot of zeros and makes the writing of numbers more compact.. As an example, 573,000,000,000,000 would be written as 5.73 x 10^14. This also allows numbers to be rounded as necessary without a bunch of 0s. For example, 573,261,578,357,198 to three significant figures would be 573,000,000,000,000 which would be written as 5.73 x 10^14 (as above).
Any rational number is either a repeating decimal, or a terminating decimal.
In a vacuum, light travels about 3,725,648 miles every 20 seconds. In scientific notation this distance is expressed as: 3.725648 x 106 miles per 20 seconds.
in scientific notation, every number is written as a decimal number that is greater then 0 and less then 10, times 10 to the power of x. eg. 987.27 in scientific notation would be 9.8727 x 102 (102 =100 and 9.8727 x 100 = 987.27) while 0.00062 would be 6.2 x 10-4

All areas. Scientific notation is useful whenever you have very small or very large numbers, and these appear in some aspect of every branch of science.

2.44 x 10^3 or 2.440 x 10^3In scientific notation, there is only one number to the left of the decimal point which is not zero. The resulting decimal is multiplied by ten to a certain power; for every place the decimal point was moved left, the power is increased by one (204 = 2.04 x 10^2, since the decimal point not shown to the immediate right of 4 moved left twice to make 204 2,04). Likewise, for every place the decimal point must move to the right, the power increases by one, but it also becomes negative as well. (.02 = 2. x 10^-2) Another way of looking at this is that you are moving a negative amount of spaces to the left. To put 2,440 in scientific notation, move the decimal place to the left 3 times; the resulting number is 2.440 x 10^3. Since there is a zero on the end and there is no decimal place (it isn't written 2440.), 2,440 is ambiguous; we don't know if the end zero is a significant figure or not, so technically it could be either 2.440 x 10^3 or 2.44 x 10^3; we can't know for sure if the person who measured 2440 measured it our to the last four or to the 0.
Notation with a decimal point is called decimal for a reason. Every step after the point is a fraction of 10 more.0.1 = 1/100.01 = 1/1000.001 = 1/1000 etc.0.01 = 1/100 so 0.07 = 7/100
no cuz i said no
Yes, except for zero. Numbers larger than 1 have positive exponents, and numbers between 0 and 1 have negative exponents. Negative numbers would just have a '-' in front.
scientific notation is used when extremly high amounts of one type of object is being used such as money or chemicals. it is also always used in chemistry because some of the stuff as a chemist is calculated in moles.
