Question

Following are the steps to represent the $\sqrt{7}$ on numberline. Arrange them in order.
1) Take A so that $l\left(OA\right)=1$. Draw $AB\perp OA$.
2 Take E on Line so that $OE=OD$. Draw $EF\perp OE,l\left(FE\right)=2$
3) Take G on Line so that $OG=OF$.
4) Take C on Line so that $OC=OB$. Draw $CD\perp OC$.

• A. $1,2,3,4$
• B. $2,3,1,4$
• C. $1,4,2,3$
• D. $4,3,2,1$

Answer 1

Answer: (C)

$1,4,2,3$

The correct steps are :

Step 1. Take $A$ so that $l\left(OA\right)=1$. Draw $AB\perp OA$

Step 2. Take $C$ on line so that $OC=OB$. Draw $CD\perp OC$.

Step 3. Take $E$ on line so that $OE=OD$. Draw $EF\perp OE$, $l\left(FE\right)=2$

Step 4. Take $G$ on line so that $OG=OF$.

Therefore option (C) is correct.
