Question

Locate √17 on a number line​

Answer 1

SOLUTION

We know that 16−−√=4 and 17−−√=42+12−−−−−−√

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−−√

Sol :

We know that √16 = 4 and √17 = √(42 +12 )

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.
