Question

Represent underroot 2.3 on the number line

Answer 1

Answer:

√2.3 is proved on the number line

Mark B at a distance of 1 unit from A. Find the midpoint of OB and mark it point C. ... Taking A as center and AD as radius, draw an arc intersecting number line at E. BE is √2.3.

Step-by-step explanation:

√2.3 is proved on the number line

Step-by-step explanation:

Mark a line segment OA = 2.3 cm on number line

Mark B at a distance of 1 unit from A

Find the midpoint of OB and mark it point C

Draw a semi-circle OB while taking C as its center

Draw a perpendicular to line OB passing through point A

Let it intersect the semi-circle at D

Taking A as center and AD as radius, draw an arc intersecting number line at E

BE is √2.3  

Now draw a new number line of same size as that of the previous  

Take the compass and draw an arc on the new number line by keeping the pointed end at A and pencil end at E

The intersection of arc is named as F

Now OF = √2.3
