Answer» Given : root 4 .1 √4.1 To find : represent on NUMBER line Solution: Step 1 : Draw a number line AOB ( O being 0) Step 2 : Take a length of 4.1 cm from O on left side mark it M Step 3 : Take 1 cm from O on right side , mark it N Step 4 : Using suitable compass width draw arcs on both sides of MN taking M & N as center & intersecting at X & Y Step 5 : join X & Y intersecting MN at P Step 6 : Draw a semicircle taking P as center & PM = PN as radius ( compass width) Step 7 : Draw a right angle at AO such that it intersect semicircle at Z OZ = √4.1 Step 8 : Taking compass width = OZ and taking O as center cut the number line on right side at C point C represent √4.1 on a number line Mathematical proof Semicircle radius = (4.1 + 1)/2 = 5.1/2 ( hypotenuse) 5.1/2 - 1 = 3.1/2 = Base Perpendicular OZ² =( 5.1/2)² - (3.1/2)² => OZ² = (5.1/2 + 3.1/2) (5.1/2 - 3.1/2) => OZ² = 4.1 => OZ = √4.1 Learn more: 1.
