Ans. To describe the position of a table lamp placed on the table, let us consider the table lamp as P and the table as a plane. Now choose two perpendicular edge of the table as the axes OX and OY. Measure the perpendicular distance ‘a’ cm of the lamp from OY. Measure the perpendicular distance ‘b’ cm of P (lamp) from OX.

Thus, the position of the table lamp P is described by the ordered pair (a, b).

put a= 1000. b=2
{tex}=1000^2 + 2^2 -2×1000×2{/tex}
= 1000000 + 4 -4000

Construct BD of 1 unit length perpendicular to OB as fig. Join OD By Pythagoras theorem, OD=(2)2+12=2+1=3 Using a compass, with centre O and radius OD, draw an arc which intersects the number line at the point L right side to 0. Then ′L′ corresponds to 3. From this we can conclude that many points on the number line can be represented by irrational numbers also. In the same way, we can locate n for any positive integers n, after n−1 has been located.
