A power of ten with a positive exponent, such as 10 5, means the decimal was moved to the left.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. You can show that you moved it 6 places to the right by noting that the number should be multiplied by 10 -6. The table shows several examples of numbers written in standard decimal notation (left-hand column) and in scientific notation (right-hand column). A player must correctly guess five questions, starting at 1,000, with and each answer increasing in value by multiples of 10. A game show in which contestants compete for 10 million by trying to guess the results of nationwide surveys. You had to move it 6 places to the right to change 0.0000073 to 7.3. Power of 10: With Drew Carey, Judy Beil, Daniele Donato, Amber Tomcavage. Next, count how many places you moved the decimal point.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.They're also easy to represent in exponential form (as I show you in Chapter. Scientific notation can be used to turn 0.0000073 into 7.3 x 10 -6. Powers of ten are easy to work with, especially when you're multiplying and. 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.
If you keep moving the decimal point to the left in 2,890,000,000 you will get 2.89.
POWER OF TEN SHOW HOW TO
The following diagram shows how to multiply and divide. In scientific notation, you move the decimal place until you have a number between 1 and 10. When dividing by powers of 10, move the decimal point one place to the left for each power of ten. When n is equal to 0, the power of 10 is 1 that is, 10 0 1. When n is less than 0, the power of 10 is the number 1 n places after the decimal point for example, 10 2 is written 0.01. 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, 10 6 is written 1,000,000. Scientific notation is a way to make these numbers easier to work with. A power of 10 is as many number 10s as indicated by the exponent multiplied together. 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.
