Answer 1

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196

Explanation:

1x1=1

2x2=4

3x3=9

4x4=16

5x5=25

6x6=36

7x7=49

8x8=64

9x9=81

10x10=100

11x11=121

12x12=144

13x13=169

14x14=196

Perfect squares are when the same number multiplied is multiplied by itself, it also has to be an integer, meaning a whole number.

Answer 2

see below

Explanation:

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

6² = 36

7² = 49

8² = 64

9² = 81

10² = 100

11² = 121

12² = 144

13² = 169

14² = 196

15² = 225 (this is greater than 197 hence not included in the answer.

Hence perfect squares less than 196 ranges from 1² through 14²
