### How to convert decimal number to ScientificNotation?

In the world would i convert these decimal numbers to scientificnotation? For example, say i have a number: 12,700. Expressed in scientificnotation, this would be 1.27x10^4. I hope there is an easy way ; } } Robert Penner's - older ScientificNotation http://www.actionscript.org/forums/s...ad.php3?t=1596

Question:Here is the problem: Everything around you is made up of atoms. Atoms are extremely small. An atom is about two millionth of an inch in diameter. Write this number in standard form and then in scientific notation. I'll give 10 points (if I ever figure out how to...) and best answer to the person who helps me with this question and doesn't give me a stupid answer. How do you give someone 10 points?

Answers:Two millionths is .000002 in standard (decimal) notation. In scientific notation a number is written as a number between 1 and 10 multiplied by a power of 10. In this example, .000002 = 2 x 10 ^ -6 Cheers, Nicholas

Question:Can someone please explain to me.. im so confused. for example: express these in equalities in abs value notation: -8<=x<=-2 x>3 or x<-3

Answers:FYI, it really helps to draw the number line for the inequality problems. -8 x -2 x is between -8 and -2, so the |x| is between 2 and 8, since |-8|=8 and |-2| =2. So the answer is 2 |x| 8 ---------___--------- x>3 or x<-3 x is either greater than 3 or less than -3. The only place on the number line where x cannot be is at or between -3 and 3. The absolute value of any negative number is the same as the absolute value of the opposite positive number. So the smallest value that |x| can be is a little larger than 3. So the answer is |x|>3

Question:in the scientific notation 4.140625 x 10^-3 the 10 with the exponent should equal .001 to come out to the right answer. (.004140625) but 10^-3 equals .01 when i figure it out. (10 divided by 1000). the rules for scientific notation say that the exponent describes a move of the decimal point. so negative 3 would be three to the left. and that is correct, by why does 10^-3 work out to .01 when i do the math for the 10 and the exponent only? the notation doesn't seem to make sense to me.... please help!!!!!!!!!!!

Answers:10 = 1000 10 = 100 10^1 = 10 10^0 = 1 10^(-1) = 1/10 = 0.1 10^(-2) = 1/10 = 1 / 100 = 0.01 10^(-3) = 1/10 = 1 / 1000 = 0.001 etc Hope this helps.

### Scientific Notation - Pre Algebra

Scientific Notation - Pre-Algebra mrpilarski.wordpress.com Scientific Notation is used when numbers that are very large. The numbers do not have to be just large in value, just with many place values. Numbers like 152000000000 and 0.0000000000456 are good examples of numbers that would be expressed using scientific notation. Also, this lesson models how to multiply numbers in scientific notation. Lesson 4.7

### Scientific Notation - Explained!

Scientists have to work with some very large and some very small numbers. To represent these numbers more easily, they use scientific notation. Scientific notation relies on powers of 10. This video gives examples of how to represent a large and small number and explains powers of ten.

### Algebra Scientific Notation

To change a whole number that is greater than one from standard form to scientific notation: Copy all the nonzero digits and the zeros that are between nonzero digits (if there are any). Place the decimal point after the first nonzero digit. Multiply this number by a certain power of ten. To determine the exponent, simply count all the digits that are after the first nonzero digit in the standard form. To change a positive decimal that is less than one from standard form to scientific notation Copy all the nonzero digits and the zeros that are between nonzero digits (if there are any). Place the decimal point after the first nonzero digit. Multiply this number by a certain power of ten. The exponent is a negative number. To determine the exponent, simply count all the digits that are between the initial position of the decimal point, and the first nonzero digit in the standard form. In the scientific notation, place the result of your counting at the exponent with a negative sign in front of it. Thanks for watching.
