Represent 3/2 on number line
Represent 3/2 on number line- If we express √2 in the decimal form, we observe that it does not terminate and is nonrecurring Such numbers are called irrational numbers The numbers √2 , √3 , √6 , √7 , 2 √3 , 2 – √3 , √2 √3 etc, are examples of irrational numbers All nonterminating and nonrecurring decimal number are irrational numbers If a and b are rational numbers and (√11 − √7)/(√11 √7) = a – b√77, find the value of a and b Finding irrational numbers b/w two numbers;
As an example, let us locate √ 2 on the number line This is easy Remember that √ 2 is the length of the diagonal of the square whose side is 1 unit (How?)Simply construct a square and transfer the length of one ofThis can be written as √10 = (√3 2 1 2) The construction steps are shown below Take a line segment AO = 3 units on x axis Here consider 1 unit = 2 cm Draw a perpendicular on O, name it as OC such that OC = 1 unit Now, join AC with √10 Now, take A as centre and AC as radius, draw an arc which cuts the x axis at point ERepresent √32 geometrically on the number line Report Posted by Riya Singh 3 years, 2 months ago CBSE > Class 09 > Mathematics 1 answers Prashant Chaudhary 3 years, 2 months ago
The number √2 is shown on a number line Steps are given to show √3 on the number line using √2 Fill in the boxes properly and complete the activity Activity The point Q on the number line shows the number A line perpendicular to the number line is drawn through the point Q Point R is at unit distance from Q on the line1 Irrational Numbers on the Number Line Where are the points on the number line that correspond to the irrational numbers? Whole numbers Numbers starting from 0 to infinity (without fractions or decimals) ie, Whole numbers= 0,1,2,3 Or, we can say that whole numbers have all the elements of natural numbers and zero Every natural number is a whole number;
