I just need help with 1-6

1 .8

2.5

3.3

4.8 and 9

5. 3 and 4

Step-by-step explanation:

1. 8 because 8×8=64 and 64 is closer to 66

2. 5 because 5×5=25 and 25 is closer to 27

3. 3 because 3×3=9 and 9 is closer to 13

4. 8 and9 because 8×8=64and 9×9=81 and 78 is located between 64and 81

5.3 and 4 because 3×3=9 and 4×4=16

And 12 is located between 9 and 16

6 . I am sorry I don't know

did you get the answer yet?

step-by-step explanation:

check above link.
