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

Answer»

The number of members in a set A is the Cardinal number of the set A and is denoted by n(A)

62430.

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

Tnuts lab)" - a"b" by using principle of mathema12. Prove the rule of exponents (ab)" = ananinduction for every natural number.hot

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.
