True False
62 = 12

82 = 8×8

12−−√= 6 because 6×2 =12

49−−√ = 7 because 7×7=49

Answer 1

Let's evaluate each statement one by one:

1. 62 = 12

   • FALSE (62 is not equal to 12; it is 6 times 10 plus 2.)

2. 82 = 8×8

   • TRUE (82 represents 8 squared, which is indeed 8 times 8, or 64.)

3. 12−−√= 6 because 6×2 =12

   • FALSE (The square root of 12, denoted as √12, is not 6. The correct answer should be √12 ≈ 3.46, since 3.46 × 3.46 = 12.)

4. 49−−√ = 7 because 7×7=49

   • TRUE (The square root of 49 is 7, since 7 times 7 equals 49.)

So, the answers are:

1. FALSE
2. TRUE
3. FALSE
4. TRUE
