11. Know WHAT gets repeated #1#1

12. -7 2 = -77 (-7) 2 = -7-7 5c 3 = 5ccc (5c) 3 = 5c5c5c 5c 3 a = 5ccca

13. Know anything to the zero is 1 #2#2 9090 = 1 (-9) 0 = 1 (5c) 0 = 1 (blah blah blah) 0 = 1 6a 0 = 61 = 6

14. Know what a negative power means. #3#3 2323 = 1222 2 -3 = 1÷2÷2÷2 = 8 = 1 2323 = 1 8

15. Know how to deal with a negative power #3#3 2 -3 = y -7 = 4y -7 = = = = -3m -2 a -3m 2a -3 7a -4 -5b -3 1 2323 1 y7y7 4 y7y7 -3 am 2 -3ma 3 2 7b 3 -5a 4

16. Know product, quotient & power rules. #4#4 a8a5a8a5 = a 8+5 = a 13 = a 8-5 = a3a3 a8a8 a5a5 (a 8 ) 5 = a 85 = a 40

17. Be care when subtracting exponents. #4#4 = m5m5 m7m7 m -2 1 = 1 m2m2 = b -7 b4b4 b -7-4 1 = b -11 1 = -5m 9 m 15 -5m 9-15 1 = -5m-6 1 = a7c5a7c5 a 2 c 11 a 5 c -6 1 = a5a5 c6c6 = a2c3a2c3 a 9 c -2 a -7 c 3- -2 1 = c 5 a7a7 = 1 b 11 = -5 m6m6

18. Know how to DISTRIBUTE the product & quotient rules. #5#5 (a 6 b 9 ) 3 = a 18 b 27 (3y 4 ) 2 = 32y832y8 (2 3 c 5 ) 7 = 2 21 c 35 4 3 3 = 4 9 m7m7 m 21 y 4 -5 = y -20 z2z2 z -10 = z 10 y 20

19. Know how to SIMPLIFY using all the previous rules. #6#6 If all else fails, MOVE NEGATIVE EXPONENTS, EXPAND, CANCEL, & SIMPLIFY. = a 0 b -3 cc -1 -5b -2 = 6b 20 a 8 5b 7 a -9 6b 20-7 a 8- -9 5 = 6b 13 a 17 5 = a0b2ca0b2c -5b 3 c 1 = 1bbc -5bbbc 1 -5b

20. Recognize Scientific Notation. #7#7 3.9 x 10 8 vs..39 x 10 8 3.9 x 10 0 vs. 3.9 x 5 -8 3.9 x 10 -8 vs. 3.9

21. Go from Standard Notation to Scientific Notation #8#8

22. Go from Standard Notation to Scientific Notation #8#8

23. Go from Scientific to Standard #8#8 = 61000000. 6.1 x 10 7 6.1 x 10 -7 =.00000061

24. Multiply, Divide & Add Scientific Numbers #9#9 4.8 x 10 8 3.2 1.5 10 2+6 (5.1 x 10 5 ) ( 5 x 10 3 ) = 1.02 x 10 5-3 = 1.02 x 10 2 (2.38 x 10 4 ) + (1.7 x 10 4 ) (2.38 + 1.7) (10 4 ) = 4.08 x 10 4 (3.2 x 10 2 )(1.5 x 10 6 ) RULE: (scalar scalar)(10 a+b ) RULE 10 a (scalar scalar) RULE 10 a (scalar ± scalar)
