Calculate and verified root six is a rational number

Answer»

<P>ASSUME that √6 is rational.

Then √6 = p/q where p and q are co-prime integers.

√6^2 = 6 = p²/q²

p² = 6q²

∴ p² is an even number since an even number multiplied by any other INTEGER is also an even number. If p² is even then p MUST also be even since if p were odd, an odd number multiplied by an odd number would also be odd.

So, we can replace p with 2k where k is an integer.

(2k)² = 6q²

4k² = 6q²

2k² = 3q²

Now, we SEE that 3q² is even. For 3q² to be even, q² must be even since 3 is odd and an odd times an even number is even. And by the same argument above, if q² is even then q is even.

So both p and q are even which means both are divisible by 2. But that means they are not co-prime, contradicting our assumption so √6 is not rational.

he present ages of Chetna and Shikha are in the ratio of 5:7 respectively. After 7 years, their ages will be in the ratio of 11:14 respectively. What is the difference between their ages?

Answer»

CHETNA : Shikha = 5:7


5x 7X


After 7 years, Ratio = 11:14


(5x+7)/(7x+7) = 11/14

Cross Multiplication,

70x + 98 = 77X +77

7x = 21

x= 3


Present age of Chetna = 5x = 5*3 = 15 years

Present age of Shikha = 7x = 7*3 = 21 years



Difference between ages = 21 - 15 = 6 Years

A rectangular piece of paper has a length of 14cm and a breadth of 12cm. A Square piece of paper of perimeter 24cm is cut off from it. Find the area of the piece of paper left.

Answer»

Area of rectangular piece of PAPER=14cm×12cm=168cm^2.
PERIMETER of a square piece of paper =24=4×side of the square=>side of the square =6cm. Area of the square piece of paper =6cm×6cm=36cm^2.So area of left piece of paper=Area of rectangle-Area of square=168cm^2-36cm^2=132cm^2.

What is the smallest no. by which 13068 should be divided,so the quotient is a perfect square?

Answer»

Let's factorize 13068 by LCM.


2 | 13068

2 | 6534

3 | 3267

3 | 1089

3 | 363

11 | 121

11 | 11

| 1


13068 = 2² X 3³ x 11²


2² x 3³ x 11² divided by 3 gives 2² x 3² x 11² = (2 x 3 x 11)² = 66².


So 3 is the smallest number by which 13068 is divided to get a perfect square as quotient.


13068 ÷ 3 = 4356 = 66²


Hope this may be helpful.


Please mark my answer as the brainliest if this may be helpful.

Plz tell me 20 or 21 or 22 both parts with full explanation

Answer»

20) ( x + 11 )²

1. you must SQUARE the x =x²

2. then multiply the x by 11 and 2, so 11 x 2 =22, 22 × X = 22x

3. then you square 11, = 11 x 11 = 121

= x² + 22x + 121


22) (5A + 2B) ³

1. you expand by,

(5a + 2b)² + (5a + 2b)


so first step you do the same thing,

2. 5a is squared = (5a)² =25a²

3. then you multiply 5a by 2b by 2, =( 5a x 2b) X2 = 20ab

4. then you must square 2b, =4b²


so you should have 25a² + 20ab +4b² + (5a +2b)

= 25a² +20ab +4b² + 5a + 2b


hope i am right and have helped :)
