Hello dear friend ☺☺
ANS-
we call the process of visualisation of representatives of numbers on the number line, through a magnifying glass, as the PROCESS OF SUCCESSIVE MAGNIFICATION.
Thus, we can say that every real number is represented by a unique point on the number line. further , every point on the number line represents one and only one real number.
Example -
Q. Show how √5 can be represented on the number line??
Sol.
we know that ,
√5 = √4+1 = √2²+1¹
Draw right angled triangle OQP,
OQ = 2 units
PQ = 1 units
and angle OQP = 90°
Now , by using Pythagoras theorem, we have
OP² = OQ² + PQ² = 2²+1²
=>OP = √4+1 = √5
Now, take O as center OP = √5 as radius,
Draw an Arc , which interests the line at point R
Hence , the point R represents √5 .
Hope it's helps you.
