1 Guided Notes for lesso P. Properties of Expoets If a, b, x, y ad a, b, 0, ad m, Z the the followig properties hold:. Negative Expoet Rule: b ad b b b Aswers must ever cotai egative expoets. Examples: 5 b) 4. Zero Expoet Rule: 0 b Examples: 0 7 b) 0 5 c) 0 5. Product Rule: m m b g b b - keep the base ad the expoets Examples: g b) x 7 g x 4. Quotiet Rule: b b m m b - keep the base ad the expoets. Examples: 4 b) x 5 x

2 m 5. Power to a Power Rule b m b - keep the base ad the expoets. Examples: 5 b) x 4 6. Product to a power: ab Note well: a b a b ad a b a b a b - raise both bases to the same power. Examples: y 4 5 b) x y 7. Quotiet to a power: a b a b - raise both bases to the same power. Examples: 5y 4 b) x y

3 ) No paretheses. ) No powers raised to a powers. ) Each based occurs oly oce. 4) No egative expoets. 5) Simplify umerical expressios. Simplifyig Expoetial Expressios Examples: Simplify the expressio. 8 4 x y 4 5 b) x y c) 7xy x y d) 6x y 5 xy e) 5xy 6 8 5xy 4 f) 00x 0x y y 6 4 g) 4x d y g 7 4 h) 5x y 8 4 5

4 Defiitio: A umber is writte i if it is of the form where a 0 ad Z. Examples : Write i stadard form (decimal form) b) c).7 0 d) Example : Write i scietific otatio. 4,970,000,000,000 b) To multiply umbers writte i scietific otatio:. Multiply the decimal parts first. (use your calculator, if ecessary). Usig the rules of expoets, multiply the powers of te. (add the expoets). Be sure your fial aswer is i scietific otatio b) c) d) e) f)

5 To divide umbers writte i scietific otatio:. Divide the decimal parts first. (use your calculator, if ecessary). Usig the rules of expoets, divide the powers of te. (subtract the expoets). Be sure your fial aswer is i scietific otatio Examples: Fid the quotiet, express aswers i scietific otatio b) c) d) e) f)

9 Guided Notes for lesso P.7 Absolute Value Equatios Absolute Value: Defiitio: a meas the distace the umber a is from o a umber lie. Solvig Absolute Value Equatios: If X is ay algebraic expressio ad c Z, the the solutios to X care foud by solvig the equatios ad. Example Solve the equatio. x 5 b) x 7 c) x 8 4 d) x 5 e) 7 4 x f) 4 5x 7 9

10 Guided Notes for lesso P.9 Iequalities ad Absolute Value Equatios ad Iequalities To solve a iequality meas to fid all the possible values of the variable that makes the iequality true. To solve a iequality you use the same iverse operatio(s) to both sides of the iequality with oe slight glitch. Keep i mid you wat the variable all aloe o oe side of the iequality. Whe a iequality is multiplied or divided by a positive umber the iequality sig remais uchaged. Example to illustrate: 5 6 true 50 5 true 5 6 multiply by 50 5 divide by 5 0 < true < 7 true Whe a iequality is multiplied or divided by a egative umber the iequality sig is reversed. Example to illustrate: 5 6 true 50 5 true 5 6 multiply by 50 5 divide by 5 0 < false true 0 > 7 false 0 7 true Examples: Solve each of the followig ad graph your solutio o a umber lie. x 5 b) x 5 c) 4 6 d) 8 0

11 x e) 0 f) x 08 g) 6x 5 57 h) 4x 40 7x 65 i) x 7 5x j) 5x 9 i) x 8

12 Three ways to display solutios to iequalities: Set builder Notatio (used for Alg ) Iterval Notatio (used i pre-calc o up) Graph (used for either Alg or pre-calc o up) x a x b x a x b x x a x x a x x b x x b xx

21 Guided Notes for lesso 0.5 The Biomial Theorem Defiitio: A is a two termed algebraic expressio. Defiitio: Whe ay biomial is raised to a positive itegral power, the result is called a Illustratio: Expad x y x y x y x y x y x y x x y y x x y xy x y xy y x x y x y y A few thigs you should otice i the expasio of x y ) the x s decrease i power,,, 0 ) the y s icrease i power 0,,, x x x x term by term. y y y y term by term. : ) the expoets o x ad y always add up to for each term. 4) the umber of terms (4) is oe greater tha the expoet. 5) there are coefficiets o the two middle terms Where the coefficiets of a biomial expasio come from? Defiitio: The coefficiet of ay term of biomial expasio is called a biomial coefficiet ad is foud! by r provided r, ad r. r! r! C r is used as well to deote r. A combiatio of thigs take r at a time. Examples: Evaluate by had b) 8 5 c) 7 Example: Evaluate with your calculator 9 9 b) 7 c) 5 0

22 The Biomial Theorem: For ay moomial expressio a ay moomial expressio b, ad r, : a b a b a b a b... a b a b a b Examples: Expad the expressio. (write small) x 4 b) x remember that x x( ) c) x y 5 make sure it s the ad the x that are raised to the expoets.

24 Cosider the expasio of x y x x y xy y. If we just wated the secod term of its expasio without expadig it, how could we fid it? It would be x y x y For ay moomial expressio a ay moomial expressio b, ad r, The rth term of a Biomial Expasio without expadig is: r r a b r Examples: Fid the give term of the epasio with out expadig it. x 5 (third term) b) 6 8 x (fourth term) c) x 5 6 (sixth term) d) x 7 9 (secod term) 5 e) 4 x y (third) 4
