Algebra 2 6-1 Exponent Rules Obj: able to multiply monomials and to simplify expressions involving powers of monomials Write the following without exponents, then simplify 1. (x3)(x2) 2. (d)(d2) = ∙ ∙ ∙ ∙ Guidelines for simplifying exponents. Assume that no variable is equal to zero. 1. No power of a power 2. Each base appears exactly once 3. No negative exponents 4. Fractions are simplified (no decimal answers) = Power of a Product 3. (w3) (w2) For any number a, and all integers m and n: (am )(an )= 4. (4b5) (1b3) Write out the number of times the base in parentheses is used as a factor and simplify 5. (f 2)3 6. (g3)4 = ∙ ∙ = Power of a Power 7. (y5) 4 For any number a, and all integers m and n: (am) n = 8. (23) 2 Write out the number of times the base in parentheses is used as a factor and simplify 9. (2x2)3 10. (4m5)2 =2 ∙ 2 ∙ 2 = Power of a Monomial 11. (-2a2b3)2 For all numbers a and b, and all integers m, n, & p: (ambn)p = 12.(4a2b3)4 Rewrite each numerator and denominator without exponents, then simplify. Assume all denominators are not equal to zero. 13. = m5 14. m3 Guidelines for simplifying exponents. a7 Assume that no variable is equal to zero. 1. No power of a power 2. Each base appears exactly once 3. No negative exponents 4. Fractions are simplified (no decimal answers) a3 ∙ ∙ ∙ ∙ ∙ ∙ = Quotient of Powers For all integers m and n, and any nonzero number a: am an 15. a 5b 7 16. a 3b 2 Simplify using the quotient of powers rule 17. d 18. d3 y 5 Negative Exponents d3 d3 20. 2x0 Simplify using the quotient of powers rule y d −6 For any nonzero number a : a0 = 19. (2x)0 3 d3 Write without exponents and simplify 3 Zero Exponent 21. = Write without exponents and simplify 22. y3 y5 For any nonzero number a and any integer n: a –n = a −n = 1 & 1 = a −n Simplify so that there are no negative exponents in your answer. 23. w3 w 24. 8 x 2 y −3 z 4 x −3 z 6 Rate yourself on how well you understood this lesson. I have no clue what to do even if somebody is explaining the problem to me 1 What do I still need to work on? I can do it if someone is walking me through the problem I can kind of do it on my own, but I need the help of my notes/textbook I can do it on my own I can do it on my own AND I can explain it to somebody else 2 3 4 5
