Step-by-step explanation:

The objective is to represent 5–√

on the number line.

We will first consider the number line which is made on the x

-axis.

After this consider two points on the number line, zero is represented by O and 2 is represented as A. Now, draw a perpendicular on the point A and will name the line as AX.

Next, we will take 1 unit on the line AX and mark that point as B.

Now, we will apply the Pythagoras theorem on the triangle OAB and can find the value of line OB.

Thus, we have,

OA = 2

and AB = 1

Hence,

⇒(OB)2=(OA)2+(AB)2⇒(OB)2=(2)2+12⇒(OB)2=5⇒OB=5–√

Thus, we get the line OB as 5–√

units.

Next, we will take O as the center and OB as 5–√

units as radius draw an arc cut the point B and touch the point C on the right side of point A.

Thus, OC = OB = 5–√

.

Hence, the figure is shown as follows:

Thus, we can conclude that point C represents 5–√

on the number line.
