Subjective Questions

Q1:

Show √3 and √5 on a number line.


Type: Short Difficulty: Easy

Show/Hide Answer
Answer: <p>Soln:</p> <p>If CA=1 unit and CB=2 units of a right angled&Delta;ACB,then</p> <p>AB<sup>2</sup>=CA<sup>2</sup>+CB<sup>2</sup>=1<sup>2</sup>+2<sup>2</sup>=5</p> <p>&there4; AB=√5</p> <p>So, an arc of radius equal to AB cuts the number line at F so that AF=√5. Similarly, in right angled&Delta;ACD, take AD=√3 units are the radius which cuts the number line at E. So that, AE=√3. The graph √5 and √3 are show on the number line alongside.</p>
