. Locate root 10 on the number line
According to the Pythagoras Theorem,
On the x-axis, draw a line segment A0=3 units, with 1 unit = 1cm .
Draw a perpendicular on O and label it OC, with 0C=1 unit.
Now, join AC with .
Draw an arc that cuts the -axis at point E, using A as the center and AC as the radius.
The line segment AE represents units as shown in the diagram
Final answer: is represented by the line segment AE on the number line
