√2 Represent the following irrational number on the number line |
| Answer» I am just telling the steps of making root 2 on a number line. You just make it. Steps are :- 1) Make a line of 1 cm and name the line AB.2) Make angle B = 90 degree.3) Open the compass on the scale and measure 1 cm. Then, cut an arc from point B and name the point as C.4) Join the line from point C to point A.5) AC = Root 26) Extend the line.7) Now measure the length of AC and put the compass on A and make a dotted line on the line AB.Now I will tell you how AC is root 2 we had calculated.By Pythagoras theorem (Hypotenuse) square = (Base) square + (Perpendicular) square( AC) square =(AB) square + (BC) square( AC) square = (1) square + (1) square( AC) square =1 + 1( AC) square = 2 AC = Root 2 Thank you. | |

Proov root 2 is not rational |
|
Answer» Rational numbers are those numbers which can be expressed in the form p/q where p and q are integers and q is not equal to 0 whereas irrational numbers cannot be expressed in the form p/q where p and q are integers and q is bot equal to 0. Root 2 = 1.4142............... and so on and it is non- terminating and non - recurring which is a property of irrational numbers. Its value is infinite that is never ending and also cannot be written in the form p/q. This proves that root 2 is not a rational number. It is an irrational number. We know that,A rational number can be written in p/q form wre as, an Irrational number cannot be written in p/q form.√2 = 0.41421356 and so on...(Non terminating, Non recurring )Value of √2 never ends So we cannot write it in p/q form..Hence, √2 is not a rational number. It is an irrational number. |

Is √2/7 irrational or rational |
|
Answer» irrational Irrational Let us assume that 2/√7 is rational number.2/√7= 2/√7 × (√7/√7)= 2√7/7. ( Rationalising)Now, 2√7/7 = p/q ( as rational no. can be written in the form of p/q)2√7= 7p/q√7= 7p/2qHere LHS is irrational but RHS is rational.This contradicts the statement.Our assumption is wrong.2/ √7 is an irrational number. |

In triangle KMN, PQ is parallel to MN. If KP/KM = 4/13 and KN = 20.4 cm. Find KQ |
| Answer» In Triangle KMN, We havePQ // MNTherefore, KP/PM = KQ/QNKP/PM = KQ/KN-KQ4/13 = KQ / 20.4 - KQ4(20.4 - KQ ) = 13 KQ81.6 - 4KQ = 13 KQ17 KQ = 81.6KQ = 81.6/17⇒ 4.8 cm.Hence, the value of KQ = 4.8 cm. | |

If x=2+√3, Find the value of x^2+1/x^2 |
| Answer» Given thatx = 2 + √31/x = 1/2 + √3= 1 × (2 - √3)/(2 + √3) (2 - √3)= (2 - √3)/(2^2 - √3^2)= (2 - √3)/4 - 3= (2 - √3)Therefore ,x^2 = (2 + √3)= (2)^2 + (√3)^2 + 2 × 2 × √3= 4 + 3 + 4√3= 7 + 4√31/x^2 = (2 - √3)^2= (2)^2 + (√3)^2 - 2 × 2 × √3= 4 + 3 - 4√3= 7 - 4√3x^2 + 1/x^2= (7 + 4√3) + (7 - 4√3)= 7 + 4√3 + 7 - 4√3= 7 + 7 + 4√3 - 4√3= 14 | |
