Answer:

A, B, C, E, D

F, G, H, I, J

Explanation:

You can go at this a couple of ways.

Consider the squares of number 1 through 9.


\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}

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
