I hope this will help you,if you need dia. then tell me.

Answer 2

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.
