Five what? If it’s 5 millimeters, the bug is quite small. If it’s 5 centimeters, the bug is quite large. If it’s 5 meters, run for cover! The point is that for a measurement to be meaningful, it must consist of both a number and a unit that tells us the scale being used. In this chapter we will consider the characteristics of measurements and the calculations that involve measurements. 1 Scientific Notation OBJECTIVE: A measurement must always consist of a number and a unit. 1 centimeter Number Unit To show how very large or very small numbers can be expressed as the product of a number between 1 and 10 and a power of 10.

Because we moved the decimal point five places to the left, the power of 10 is positive 5. 38 ϫ 105. b. 1 5 0 0 0 0 0 6 5 4 3 2 1 The decimal point was moved six places to the left, so the power of 10 is 6. 5 ϫ 106. 2 MATH SKILL BUILDER A number that is less than 1 will always have a negative exponent when written in scientific notation. Scientific Notation: Powers of 10 (Negative) Represent the following numbers in scientific notation.

Thus a substance that possessed many advantages in earthbound applications turned against us in the atmosphere. Who could have guessed it would turn out this way? S. chemical industry is leading the way to find environmentally safe alternatives to CFCs, and the levels of CFCs in the atmosphere are already dropping. The saga of the CFCs demonstrates that we can respond relatively quickly to a serious environmental problem if we decide to do so. Also, it is important to understand that chemical manufacturers have a new attitude about the environment—they are now among the leaders in finding ways to address our environmental ills.
