Study Notes
Estimating Square Roots
- The radical sign is √
- The radicand is the number under the radical sign
- To estimate √3:
- Find the nearest perfect square to 3, which is 4
- √4 = 2
- Divide the radicand (3) by the answer from step 2 (2). This gives 1.5
- Add the answers from steps 2 and 3 (2 + 1.5 = 3.5)
- Divide the answer from step 4 by 2 (3.5 / 2 = 1.75)
- Therefore, √3 ≈ 1.75
Plotting Irrational Numbers
- Irrational numbers can be plotted on a number line using the concept of approximating square roots.
