(4 points)
True False
49−−√ = 7
because 7×7=49

12−−√= 6
because 6×2 =12

62 = 12


82 = 8×8

Answer 1

Let's evaluate each statement one by one:

1. Calculators are not allowed in Unit 2.

   • This statement cannot be verified as TRUE or FALSE without context, so I will not provide an answer.

2. 49−−√ = 7 because 7×7=49

   • This statement is TRUE. The square root of 49 is indeed 7, since \(7 \times 7 = 49\).

3. 12−−√= 6 because 6×2 =12

   • This statement is FALSE. The square root of 12 is not 6; it is approximately \(3.464\).

4. 62 = 12

   • This statement is FALSE. \(6^2 = 36\), not 12.

5. 82 = 8×8

   • This statement is TRUE. \(8^2 = 64\), and \(8 \times 8 = 64\).

In summary:

1. Undetermined
2. TRUE
3. FALSE
4. FALSE
5. TRUE
