expand by expressing powers of 10 in exponential form:(i)172 (ii)5643 (iii)56439 (iv)176428
(i) 172 = 1 * 102 + 7 * 101 + 2 * 100
(ii)5643 = 5 * 103 + 6 * 102 + 4 * 101 + 3 * 100
(iii) 56439 = 5 * 104 + 6 * 103 + 4 * 102 + 3 * 101 + 9 * 100
(iv) 176428= 1* 104 + 7 * 103 + 6 * 102 + 4 * 102 + 2 * 101 + 8 * 100
Hope you understood
