Show that the square of any positive integer is of the form 3m or 3m+1? |
|
Answer» Let a be any odd positive integer.We apply the division lemma witha and b = 3 .Since 0 ≤ r < 3 , the possible remainders are 0 , 1 and 2 .That is , a can be 3q , or 3q + 1 , or 3q + 2 , where q is the quotient .Now ,a² = ( 3q )² = 9q²Which can be written in the form= 3 ( 3q² )= 3m , [ since m = 3q² ]It is divisible by 3 .Again ,a² = ( 3q + 1 )²= 9q² + 6q + 1= 3( 3q² + 2q ) + 1= 3m + 1 [ since m = 3q² + 2q , 3( 3q² + 2q ) is divisible by 3 ]Lastly ,a² = ( 3q + 2 )²= 9q² + 12q + 4= ( 9q² + 12q + 3 ) + 1= 3( 3q² + 4q + 1 ) + 1Which can be written in the form3m + 1 , since3( 3q² + 4q + 1 ) is divisible by 3.Therefore ,The square of any positive integer is either of the form 3m or 3m + 1 for some integer m . Let 3 be divisor and solve it |

√5 is irriational |
|
Answer» Yes it is irrational Let us assume that √5 is a rational number.we know that the rational numbers are in the form of p/q form where p,q are intezers.so, √5 = p/q p = √5qwe know that \'p\' is a rational number. so √5 q must be rational since it equals to pbut it doesnt occurs with √5 since its not an intezertherefore, p =/= √5qthis contradicts the fact that √5 is an irrational numberhence our assumption is wrong and √5 is an irrational number.\xa0 Yes Therefore, it can be written in the form of p/q. √5=p/q........ equation 1On squaring both sides(√5)^2=[p/q]^25=p^2/q^2q^2=p^2/5. ..............2Clearly, p is divisible by 5Now put q=5a in equation 2 Therefore, 25a^2=5p^2Therefore,. q is also divisible by 5 Our assumption was wrong √5 is an irrational no. Hence, proved Let √5 be a rational no. |
