Answer 1

(i) Given 20068

20068 = 2 x 104 + 0 x 103 + 0 x 102 + 6 x 101 + 8 x 100

(ii) Given 420719

420719 = 4 x 105 + 2 x 104 + 0 x 103 + 7 x 102 + 1 x 101 + 9 x 100

(iii) Given 7805192

7805192 = 7 x 106 + 8 x 105 + 0 x 104 + 5 x 103 + 1 x 102 + 9 x 101 + 2 x 100

(iv) Given 5004132

5004132 = 5 x 106 + 0 x 105 + 0 x 104 + 4 x 103 + 1 x 102 + 3 x 101 + 2 x 100

(v) Given 927303

927303 = 9 x 105 + 2 x 104 + 7 x 103 + 3 x 102 + 0 x 101 + 3 x 100
