Answer:
A, B, C, E, D
F, G, H, I, J
Step-by-step explanation:
You can go at this a couple of ways.
Consider the squares of number 1 through 9.
[tex]\begin{array}{cccccccccc}n&1&2&3&4&5&6&7&8&9\\n^2&1&4&9&16&25&36&49&64&81\end{array}[/tex]
Then when the number under the radical is close to n², the root on the number line will be close to n.
The other way you can do this is to find the square root using your calculator.
- √10 ≈ 3.2 ⇒ A
- √35 ≈ 5.9 ⇒ B
- √48 ≈ 6.9 ⇒ C
- √71 ≈ 8.4 ⇒ E
- √54 ≈ 7.3 ⇒ D
- √19 ≈ 4.4 ⇒ F
- √89 ≈ 9.4 ⇒ G
- √6 ≈ 2.4 ⇒ H
- -√20 ≈ -4.5 ⇒ I
- -√2 ≈ -1.4 ⇒ J
