Chapter 2 Roots 2.6 Recognizing Square Root and Cube Root Values on a Number Line Square root values can be plotted on a number line. Study the example below. s Example 11: Plot the value of 3 on the number line below. s Step 1: We learned on page 36, that 3 is around 1=75. s Step 2: Plot 3 around 1=75. 0 1 2 3 4 Plot and label the following values on the number lines given below. 0 1. L= 1 s 2 M= 2 s 5 N= 3 s 6 O= s 8 Look at the number line below. Match the letter of the number to each of the problems below. You may use a point more than once. 2. Which point is closest to the value of 3. Which point is s 64? 6. Which point is s 121? 7. Which point is closest to the value of 4. Which point is closest to the value of 5. Which point is s 52? s 81? s 125? 8. Which point is s 49? 9. Which point is closest to the value of Cube root values can also be plotted on a number line. Study the example below. s Example 12: Plot the value of 3 56 on the number line below. s Step 1: We learned on page 37, that 3 56 is around 3=85. s Step 2: Plot 3 56 around 3=85. 0 38 1 2 c American Book Company Copyright ° s 99? 3 4 s 67?
