The 2nd root of 81 or 81 radical 2 or the square root of 81 is written as sqrt 2 81 sqrt.
Square root of 17 on a number line.
Draw an arc intersecting number line at c c is represented as 17.
So the graphical representation of square root of 13 3 61 is shown below.
For example 4 9 and 16 are perfect squares since their square roots 2 3 and 4 respectively are integers.
Hence on the number line draw a at point 0 i e point a draw ab perpendicular to number line of length 9 units.
In the construction background is pythagorean theorem.
Then mark point a representing 4 on number line now construct ab of unit length perpendicular to oa then taking o as centre and ob as radius.
Draw an arc intersecting number line at c c is represented as 17.
Transcript 𝟑 on the number line represent 𝟑 on number line let s draw the number line using pythagoras theorem ob2 op2 pb2 ob2 2 2 12 ob2 2 1 ob 3 example 4 locate 3 on the number line for drawing 3 we consider pythagoras theorem.
Hope its help u.
We know that 16 4 and 17 4 2 1 2 mark point a representing 4 on number line now construct ab of unit length perpendicular to oa then taking o as centre and ob as radius.
Down applet shows how to mark square roots of the natural numbers on the number line.
Click the animation button in the left down angle of the applet to start animation.
Since bc ab ac 10 9 ac ac 10 9 19.
It is required to plot the number square root of 13 on the number line.
From the end point b of this line draw an arc of radius 10 units intersecting the number line at point c.
Represent root 13 on the number line locate root 13 on the number line 13 on the number line.
That is we have to represent 3 61 on the number line.

Sqrt 17 is not simplifiable and is irrational.
We can calculate rational approximations like.
Since we know square root of 13 3 61.
Sqrt 17 268 65 4 1231 since 17 is prime it has no square factors so sqrt 17 cannot be simplified.
As the number 3 61 lies between 3 and 4 more towards the number 4.
