1.

If 2+5√7/2-5√7=x+√7y, find x and y.

Answer»

Answer:

5√7/2-5√7-√7y=x+2

√7(5/2-5-y)=x+2

√7(5-10-2y)/2=x+2

-√7(5+2y)/2-2=x

-√7(5+2y)-4/2=x

-√7(5+2y)-4=2x

-√7(5+2y)=2x+4

-5√7-2y√7=2x+4

-2y√7=2x+4+5√7

y=2x+4+5√7/-2√7

8.	If x3= 1728 and y3=5832, find the value ofx+1/y
Answer» Step-by-step EXPLANATION: ${x}^{3} = 1728$ $x = \sqrt[3]{1728}$ $x = 12$ ${y}^{3} = 5832$ $y = \sqrt[3]{5832}$ $y = 18$ $> \frac{x + 1}{y} = \frac{12 + 1}{18}$ $> \frac{13}{18}$

8.

If x3= 1728 and y3=5832, find the value ofx+1/y

Answer»

Step-by-step EXPLANATION:

${x}^{3} = 1728$

$x = \sqrt[3]{1728}$

$x = 12$

${y}^{3} = 5832$

$y = \sqrt[3]{5832}$

$y = 18$

$> \frac{x + 1}{y} = \frac{12 + 1}{18}$

The length of the originalsheet of paper is(a) 13 units(b) 15 units(c) 16 units(d) 30 units

Answer»

Answer:

Step-by-step explanation:

Let LENGTH of 3 pieces be x,y,z respectively

So total length=x+y+z

Now x=3+5+7/3=5

So,y=x+z/3

=>3y=3x+z

=>3y=15+z......(1)

ALSO,z=x+y......(2)

PUT eq.(2) in eq.(1)

So 3y=15+x+y

=>2y=20

=>y=10

From eq.(1)

z=10+5=15

So Total length is x+y+z=5+10+15=30units

To find : The value of x ?

Solution :

If a,b,c are in continued proportion then $b^2=ac$

Here, a=x, b=18 and c=108

Substitute the value,

$(18)^2=(x)(108)$

$x=\frac{108}{324}$

$x=\frac{1}{3}$

$x=0.33$

40.	Is division of rational numbers commutative and associative ? Justify this with the help of examples.
Answer» Answer: Commutative and Associative laws not hold in RATIONAL numbers. Step-by-step explanation: Since every INTEGER is the rational number so we take two integer 2 and 3 which are ALSO rational number with denominator 1 And 2 / 3 = 0.0666..... 3 / 2 = 1.5 so 2 / 3 ≠ 3 /2 THUS commutative law of division in rational number is not hold. Now Take 2 , 3 and 4 rational numbers with denominator 1 Then 2 / ( 3 / 4 ) = 2 / ( 0.75 ) = 2 / 0.75 = 2.6666.... ( 2 / 3 ) / 4 = ( 0.6666.... ) / 4 = 0.1666..... So 2 / ( 3 / 4 ) ≠ ( 2 / 3 ) / 4 Thus associative law of division is not hold in rational numbers.

40.

Is division of rational numbers commutative and associative ? Justify this with the help of examples.

Answer»

Answer:

Commutative and Associative laws not hold in RATIONAL numbers.

Step-by-step explanation:

Since every INTEGER is the rational number so we take two integer 2 and 3 which are ALSO rational number with denominator 1

And

2 / 3 = 0.0666.....

3 / 2 = 1.5

so

2 / 3 ≠ 3 /2

THUS commutative law of division in rational number is not hold.

Now

Take 2 , 3 and 4 rational numbers with denominator 1

Then

2 / ( 3 / 4 ) = 2 / ( 0.75 ) = 2 / 0.75 = 2.6666....

( 2 / 3 ) / 4 = ( 0.6666.... ) / 4 = 0.1666.....

So

2 / ( 3 / 4 ) ≠ ( 2 / 3 ) / 4

Thus associative law of division is not hold in rational numbers.
