Answer»

To find two rational number between -1/3 and 1/2 we have to take LCM of 2 and 3 which is 6 Now we have to multiple the both rational number to 6 at denomenater -1/3 *2/2=-2/61/2 * 3/3=3/6we get the rational numbers which are -2/6 and 3/6 so the two rational number are -1/6 , 1/6

\sqrt 6 %2B \sqrt 6 %2B \sqrt 6 %2B

Answer»

Let us assume : x= root(6+root(6 + root(6 + ………

So,

x= root(6+x)

x^2=6+x

x^2-x-6=0

(x-3)(x+2)=0

So, x=3 or -2.

But taking -2 as the answer would mean we are taking root of (-2) . Considering the fact that x belongs to the set of real numbers , we discard the solution x=-2.

So the answer is x =3.

Take some more rational numbers, add them as above and see if the two sumsare equal. We find that addition is associative for rational numbers. Thatis, for any three rational numbers a, b and c, a + (b + c) = (a + b) + c.(b) SubtractionYou already know that subtraction is not associative for integers, then whatabout rational numbers.Check for yourself.15 TiduSubtraction is not associative for rational numbers.

Answer»

LHS= -2/3 - [-4/5 - 1/2] = -2/3 - [-13/10] = -2/3 + 13/10 = 19/30RHS =[-2/3 - (-4/5)] -1/2 =[-2/3 + 4/5] - 1/2 = 2/15 - 1/2 = -11/30LHS is not equal to RHSTherefore substraction is not associative for the rational number

e ind three rational numbers lying between andHow many rational numbers can be determined betweennumbers?

Answer»

We have to find three rational number between1515and1414.Let us considerx=1515, y=1414.Let us considern = 3.

We find the value ofd.d=y−xn+1=14−153+1=1204=180y-xn+1=14-153+1=1204=180.

Thus, the three rational numbers lying betweenxandywill be given as,

(x+d), (x+ 2d) and (x+ 3d).Substituting the values ofxandd,we get,

(15+180),(15+280)and(15+380)15+180,15+280and15+380

Thus,1780,1880, and19801780,1880, and1980Therefore, the rational numbers lying between1515and1414are1780,1880,1980

Three consecutive natural numbers are such that the square of the middle numberexceeds the diference of the squares of the other two by 60. Find the numbers.15.

Answer»

Since the middle number of the three consecutive numbers is x, the other two numbers are x -1 and x +1.According to the given condition, we havex² = [(x +1)² -(x -1)²] +60x² = (x² +2x +1) -(x² -2x +1) +60 = 4x +60x² -4x -60 = 0 => (x -10)(x +6) = 0x = 10 or -6Since x is a natural number, we get x = 10Hence the three numbers are 9, 10, 11
