1 5 Sect 5. - Definitions of a 0 and a n Concept # Definition of a 0. Let s examine the quotient rule when the powers are equal. Simplify: Ex. 5 5 There are two ways to view this problem. First, any non-zero number divided by itself is, so, 5. But, using the quotient 5 rule, This says that 0. We can do this same trick with any base except for zero. Zero Exponents If a is any non-zero real number, then a 0. Simplify: Ex. a 0 Ex. b ( ) 0 Ex. c 0 Ex. d x 0 Ex. e x y 0 Ex. f (x y) 0 Ex. g (x y) 0 Ex. h ( x y) 0 a) 0 b) ( ) 0 c) 0 () (the 0 exponent only applies to ) d) x 0 () (the 0 exponent only applies to x) e) x y 0 x () x. (the 0 exponent only applies to y) f) (x y) 0 (). (the 0 exponent only applies to x y) g) (x y) 0 (). (the 0 exponent only applies to x y) h) ( x y) 0 (). Concept # Definition of a n Let s examine the quotient rule when the power in the denominator is larger than the power in the numerator.
2 5 Simplify: Ex. 5 8 There are two ways to view this problem. First, 5 and 8 56, then which reduces to 8. But, 8 5,so,. 8 But, using the quotient rule, This says that. We can do this same trick with any base except for zero. Also, since Negative Exponents If a and b are any non-zero real numbers, then a n and a n b n bn a. Note this also implies that ( ) n a n b b n b ( ) n. b n a n a In words, when raising a quantity to a negative power, take the reciprocal of the base and change the sign of the exponent. Simplify the following. Write your answer using positive exponents: Ex. 4a Ex. 4b ( ) 4 Ex. 4c Ex. 4e 5 Ex. 4d 5 ( ) Ex. 4f ( x ) Ex. 4g ( 4 y ) Ex. 4h ( ) 8 a).

Only move the factors that have negative exponents: 4x y 5a b ` 4x y 5 (negative positive is negative) 5a b 5 4b5 y 5a x. so we do not move it). (Note 4 is not an exponent, but a number d) If the exponents are already positive, do not move the factors. Only move the factors that have negative exponents: ( ) a b 7 c 5 ( 7) q 4 r v 0 8a b 7 c 5 (negative 49q 4 r 0 positive is negative) v

Properties of Integral Exponents Assume that a and b are non-zero real numbers and m and n are integers. Property Example Notes The Product Rule. a m a n a m + n x x 5 x + 5 x 8 x x 5 (x x x)(x x x x x) x 8 The Quotient Rule. b m b n bm n b The Power Rule 6 b b6 b 4 b 6 b b b b b b b b b b 4.

Definition Example Notes Zero Exponents a 0 ( 5) 0 Negative Exponents a n x 7 a n x 7 Any non-zero real number raised to the 0 power is. Take the reciprocal of the base and change the sign of the exponent.

Write your answer using positive exponents: Ex. 6a x h 7 v 8 h 9 Ex. 6b ( 7a c 4 ) Ex. 6c ( 5x y xy 4 ) a) x h 7 v 8 h 9 x h v 8 v8 x h. Ex. 6d ( 7x y 4 ) (x y ) (# product rule in the denominator) b) ( 7a c 4 ) (#4 power of a product rule) ( 7) (a ) (c 4 ) (# power rule) ( 7) a 6 c c ( 7) a 6 c 4a 6 56 c) ( 5x y xy 4 ) ( 5y x xy 4 ) ( 5y x y 4 ) ( 5y x ) ( 5 x y ) ( x y 5 ) (apply the definition of a negative exponent inside the parenthesis) (# product rule) (# quotient rule inside the parenthesis) (apply the definition of a negative exponent inside the parenthesis) (#5 power of a quotient rule)
