Question 2:
Identify the prefect squares among the following numbers;
1, 2, 3, 8, 36, 49, 65, 67, 71, 81, 169, 625, 125, 900, 100, 1000, 100000.
ANSWER:
62 = 36
72 = 49
92 = 81
132 = 169
252 = 625
302 = 900
102 = 100
Hence, 36, 49, 81, 169, 625, 900 and 100 are perfect squares.

Question 3:
Make a list of all perfect squares from 1 to 500.
ANSWER:
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
162 = 256
172 = 289
182 = 324
192 = 361
202 = 400
212 = 441
222 = 484
Hence, the perfect squares between 1 and 500 are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441 and 484.
