Yes - you can always convert numbers to scientific notation - whether they're whole numbers, or decimals.

Yes, every positive real number has a real square root. If you would write your number in scientific notation, I could tell you what the root is.

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).

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.

Then you would need lots of digits to write down some numbers, like the diameter of the known Universe in meters, the mass of the Sun in kilometers, the mass of an electron in kilograms, Avogadro's number, etc. This would be very confusing - it is much easier to have the number of digits shown in scientific notation, than having to count them every time.

Every number can be written as a quotient.Every rational number can be written as a quotient of whole numbers.

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.

Every whole number be written as a decimal; e.g 2 can be written as 2.00

• Scientific notation is used by the astronomers for their calculation of distance, speed, revolution of the planets around the sun. • The meteorologic department who have to calculate the changing weather. • Electrical engineers for their trigger operations which has ten thousand operations per second. • The players of chess games to see the number of all possible games. • Physicists use it to measure the distance between particles. • Geologists use it to measure the age of rocks.
