a) 10² = 10 • 10 = 100

11² = 11 • 11 = 121

12² = 12 • 12 = 144

13² = 13 • 13 = 169

14² = 14 • 14 = 196

15² = 15 • 15 = 225

16² = 16 • 16 = 256

17² = 17 • 17 = 289

18² = 18 • 18 = 324

19² = 19 • 19 = 361

b) 101² = 101 • 101 = 10.201

202² = 202 • 202 = 40.804

303² = 303 • 303 = 91.809

404² = 404 • 404 = 163.216

505² = 505 • 505 = 255.025

606² = 606 • 606 = 367.236

707² = 707 • 707 = 499.849

808² = 808 • 808 = 652.864

909² = 909 • 909 = 826.281
