root of a number that is a rational number.

11) Show how √5 can be repesented in the number line

12) Classroom activity ( Constructing a ‘square root spiral’) : Take a large sheet of paper and construct the ‘square root spiral’ in the following fashion. Start with a point O and draw a line segmant OP1 of unit length. Draw a line segment P1P2 perpendicular to OP1 of unit length . Now draw a line segment P 2 P 3 perpendicular to OP2 . Then draw a line segment P3 P4 perpendicular to

OP3. Continuing in this manner, you can get the the line segment Pn-1 Pn by drawing a line segment of unit length perpendicular to OP n-1 . In this manner, you will have created the points P2, P3 ,….Pn,…. .., and joined them to create a beautiful spiral depicting √2,√3,√4,…….
