A power of ten with a negative exponent, such as 10 -5, means the decimal was moved to the right.Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0 for example, 106 is written 1,000,000. A power of 10 is as many number 10s as indicated by the exponent multiplied together. Like any number written in scientific notation, 14763 has a significand (. power of 10, in mathematics, any of the whole-valued (integer) exponents of the number 10. A power of ten with a positive exponent, such as 10 5, means the decimal was moved to the left. As outlined above, there is more than one way to write 14763 as a power of 10.In expanded form: 1000 (1000 10³, note that the number of zeros is equivalent to the exponent) Multiplying by a positive power of 10 makes the number larger and multiplying by a negative power of 10 makes the number smaller. Remember: in a power of ten, the exponent-the small number above and to the right of the 10-tells which way you moved the decimal point. Powers of 10 can be written in two ways: With an exponent: 10³. You can show that you moved it 6 places to the right by noting that the number should be multiplied by 10 -6. power of 10 means 10 raised to some number e.g.: 10 2 10 10 10 5 10 10 10 10 10 10 n n factors of 10 n exponent scientific notation: Uploaded on Aug 18, 2013. You had to move it 6 places to the right to change 0.0000073 to 7.3. Next, count how many places you moved the decimal point. on powers of 10), it is far more convenient to write very large and very small numbers in a special exponential notation called scientific notation.If you keep moving the decimal point to the right in 0.0000073 you will get 7.3. First, move the decimal place until you have a number between 1 and 10.Scientific notation can be used to turn 0.0000073 into 7.3 x 10 -6. You can show that you moved it 9 places to the left by noting that the number should be multiplied by 10 9.Ģ.89 x 10 9 = 2.89 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 You had to move it 9 places to the left to change 2,890,000,000 to 2.89. Next, count how many places you moved the decimal point.If you keep moving the decimal point to the left in 2,890,000,000 you will get 2.89. To convert from the abbreviated powers of ten to the full number, look at the superscript value first (6 in this example). Now, move the decimal place until you have a number between 1 and 10.Remember that any whole number can be written with a decimal point.Then you add a power of ten that tells how many places you moved the decimal. In scientific notation, you move the decimal place until you have a number between 1 and 10. Scientific notation is a way to make these numbers easier to work with. Or it might be a small number, like 0.0000073. Sometimes, especially when you are using a calculator, you may come up with a very long number.
