Question

how to find root 7 on number line
​

Answer 1

• simple draw a line any measurement.
• now, place a point at the center name it as o and place another point from the center on the line as measurement 7 cm and name it as a.
• now same measurement draw 7cm perpendicular on the ending of the 7 cm line and name it as b.
• now join the line from o to b.
• simple now Pythagoras theorem

ob2= oa2+ab2

place the digits and get the answer as ob= 7 proved.

By Pythagoras theorem

• $= > {(hypo)}^{2} = {(side 1)}^{2} + {(side2)}^{2}$
• $= > {(op)}^{2} = {(pq)}^{2} + {(qo)}^{2}$
• $= > {(op)}^{2} = ( \sqrt{6} )^{2} + {(1)}^{2}$
• $= > {(op)}^{2} = 6 + 1$
• $= > (op) = \sqrt{7}$
