## Review of Scientific Notation
Scientific notation provides a place to hold the zeroes that come after
a whole number or before a fraction. The number 100,000,000 for
example, takes up a lot of room and takes time to write out, while 10 Though we think of zero as having no value, zeroes can make a number much bigger or smaller. Think about the difference between 10 dollars and 100 dollars. Even one zero can make a big difference in the value of the number. In the same way, 0.1 (one-tenth) of the US military budget is much more than 0.01 (one-hundredth) of the budget. The small number to the right of the 10 in scientific notation is called the exponent. Note that a negative exponent indicates that the number is a fraction (less than one). The line below shows the equivalent values of decimal notation (the
way we write numbers usually, like "1,000 dollars") and scientific
notation (10 smaller bigger Fraction 1/100 1/10 Decimal notation 0.01 0.1 1 10 100 1,000 ____________________________________________________________________________ Scientific notation 10 ## Practice With Scientific NotationWrite out the decimal equivalent (regular form) of the following numbers that are in scientific notation.
## More Practice With Scientific NotationPerform the following operations in scientific notation. Refer to the introduction if you need help.
^{2}) x (6 x 10^{3}) = 12 x 10 ^{5} = 1.2 x 10 ^{6}
Remember that your answer should be expressed in two parts, as in the
model above. The first part should be a number less than 10 (eg: 1.2)
and the second part should be a power of 10 (eg: 10 scientific notation decimal notation 25) (1 x 10
(12 x 10 Write your answer as in the model; first convert to a multiplication problem, then solve the problem. multiplication problem final answer (in sci. not.) 29) (8 x 10
Model: (3 x 10 First express the problem with the exponents in the same form, then solve the problem. same exponent final answer 33) (4 x 10
Model: (3 x 10 same exponent final answer 37) (2 x 10 ## And Even MORE Practice with Scientific Notation(Boy are you going to be good at this.)
Positively positives!
42) 1.6 x 10
Necessarily negatives! 44) 0.000553 is what in scientific notation?
Operations without anesthesia!
46) (2 x 10
47) (32 x 10
48) (9.0 x 10 Food for thought........and some BIG numbers 49) The cumulative national debt is on the order of $4 trillion. The cumulative amount of high-level waste at the Savannah River Site, Idaho Chemical Processing Plant, Hanford Nuclear Reservation, and the West Valley Demonstration Project is about 25 billion curies. If the entire amount of money associated with the national debt was applied to cleanup of those curies, how many dollars per curie would be spent? |
