Prove that V3 is irțational. |
|
Answer» V3 = 1. 7 3 2 0 5 0 Let us assume that root 3 is rational.therefore, It cab be express in the form a/b there a and b are co-prime. Now,root5 = a/broot5b=a(root5b)sq=a Squaretherefore, a square is a multiple of 5a is also a multiple of 5let a=5c for any ctherefore,=) 5b square= 5c square.=) bsquare= 5c squaretherefore b is also multiple of 5therefore a and b has a common factor 5 which is contradiction as a and b are coprimetherefore root5 is irrational v3= 1.7 3 2 0 5 0 that might work Let us assume that √3 is a rational number. then, as we know a rational number should be in the form of p/q where p and q are co- prime number. So, √3 = p/q { where p and q are co- prime} √3q = p Now, by squaring both the side we get, (√3q)² = p² 3q² = p² ........ ( i ) So, if 3 is the factor of p² then, 3 is also a factor of p ..... ( ii ) => Let p = 3m { where m is any integer } squaring both sides p² = (3m)² p² = 9m² putting the value of p² in equation ( i ) 3q² = p² 3q² = 9m² q² = 3m² So, if 3 is factor of q² then, 3 is also factor of q Since 3 is factor of p & q both So, our assumption that p & q are co- prime is wrong hence,. √3 is an irrational number |

tI |

Answer» 1/(x - x^3) = 1/[x(1 - x^2)] and 1/[x(1 - x^2)] = A/x + (Cx + B)/(1 - x^2) multiplying both sides by x(1 - x^2) gives 1 = A(1 - x^2) + (Cx + B)x For x=0 you have 1 = A -----> so A=1 For x=1 you have 1 = (C + B) For x=-1 you have 1 = (-C + B)-11 = C - B The system is C + B = 1C - B = 1 Adding these two equations together gives 2C = 2 -------> so C = 1 Back substituting shows that B=0. This means that 1/[x(1 - x^2)] = 1/x + x/(1 - x^2) Substituting into the original equation gives dy=[1/x + x/(1 - x^2) ] dx Integrating both sides gives y = ln|x| - (1/2)ln|1 - x^2| + C Since 1-x^2 = (1 - x)(1+x), this could also be written as y = ln|x| - (1/2)ln| (1 - x)(1+x) | + C = ln|x| - (1/2)ln|1 - x| - (1/2)ln|1 + x| + C |

Answer» LetP(n)P(n)be the given statement i.e.,P(n):(ab)n=anbnP(n):(ab)n=anbn We note thatP(n)P(n)is true forn=1n=1since(ab)1=a1b1(ab)1=a1b1. LetP(k)P(k)be true, i.e., (ab)k=akbk(ab)k=akbk----------(1) We shall now prove thatP(k+1)P(k+1)is true wheneverP(k)P(k)is true. Now, we have =(ab)k+1=(ab)k(ab)=(ab)k+1=(ab)k(ab) =(akbk)(ab)=(akbk)(ab)[ by (1) ] =(ak.a1)(bk.b1)=ak+1.bk+1=(ak.a1)(bk.b1)=ak+1.bk+1 Therefore,P(k+1)P(k+1)is also true wheneverP(k)P(k)is true. Hence by principle of mathematical induction,P(n)P(n)is true for alln∈Nn∈N. |
