7.

a. 3^{6-2} = 3^{4} = 81

b. 3^{6} 3^{12} = 3^{6+12} =3^{18}= 387,420,489

8.

a. 3

b. 5

9.

a. 18 = 1,2,3,6,9,18

42=1,2,3,6,7,14,21,42

fpb = 6

18 = 18, 36, 54, 72,90,108,126

42= 42, 84, 126

kpk 126

b.

42 = 1,2,3,6,7,14,21,42

63=1,3,7,9,21,63

84=1,2,3,4,6,7,12,14,21,28,42,84

fpb = 21

42= 42, 84, 126,168,210,252

63=63,126,189,252
