For instance, think about the following sequence:  \n243, 81, 27, 9, 3,   ,   ,    \nWhat are the missing three terms in this sequence? With a little trial and error, you will see that the rule for getting each term is \"divide the previous term by 3,\"and therefore the missing terms are 1, 1 /3, and 1/9. But notice, also, that these terms are just the descending  \ninteger powers of 3:  \n35 = 1 x 3 x 3 x 3 x 3 x 3  \n34 = 1 x 3 x 3 x 3 x 3  \n33 = 1 x 3 x 3 x 3  \n32 = I x 3 x 3  \n31 = 1 x 3 3° = 1  \n3-I = 1 -:- 3  \n3-2 = 1 -:- 3 -:- 3  \n= 243  \n= 81  \n= 27  \n= 9  \n= 3  \n= l  \n= l/3  \n= 1/9  \nAnd so on. If you explore this pattern, and patterns for the powers of other numbers, you will notice that some other laws clearly emerge.  \nLaw \\#2: As longas x does not equal 0, x6 = I.  \nYou can think of :(! as meaning \"l multiplied by x zero times, or not at all. \" Therefore, the result is 1.  \ne. g. , 2-3 = t ... 2 ... 2 ... 2 =  =   \n23 8  \nLaw \\#4: xm x xn = xm +n (When multiplying exponentials with equal bases, add the exponents.)  \ne.g. , x3 x x2 = (1 x x x x x x) x (1 x x x x)= l x x x x x x x x x x = x5  \nLaw \\#5: xn X y\" = (xy) n (When multiplying exponentials with equal exponents, multiply the bases.)  \nThis law follows from the Commutative and Associative Laws of Addition.  \ne.g., 43 x 72 = (1 x 4 x 4 x 4) x (1 x 7 x 7 x 7)  \n= 1 x (4 x 7) x (4 x 7) x (4 x 7)= (4 x 7)3  \ne. g. , Xx53~~ l x ~~x~~ x ~~x~~ x ~~x~~ x ~~x~~l x ~~x~~ x ~~x~~ x ~~x~~ ~~xx~~ ~~ l xxxx= x 2  \nLaw \\#7: xyn\" = (􀃱y)n (When dividing exponentials  \nwith equal exponents, divide the bases.)  \ne. g. , ~~ ~~503253~~ = [ ~~5025~~ ~~ )3 = 23 = 8  \ne.g. , (x3)2 = (1 x x3 x x3) = (1 x (1 x x x x x x) x (1 x x x x x x)) = 1 x x x x x x xx x x x x = x6  \nLaw \\#9: x;;- = efX  \nCHAPTER 9 I THE SAT MATH: ADVANCED MATHEMATICS 393  \nProof: This follows directly from Law \\#8 .

For instance, because 23 = 8, we can say that 2 is the \"third root \" or \"cube root\" of 8 (2 = if8 ) .  \nLaw \\#9 of exponentials shows us that radicals (or \"roots\") can be expressed as exponentials.
