Certainly, I'd be happy to help with this problem.

The given text presents a experiment in generating big numbers by multiplying consecutive integers. Now, let's try to determine the highest power of 3 that is a factor of the number N.

First, let's break N into primes. We notice that the numbers 19, 67, 101, 139, 179, 221, 263, 295, 327, 359, 391, 423, 455, 487, 519, 541, 563, 585, 597, 609, 611, 613, 617, 621, 623, 625, 627, 629, 631, 633, 635, 637, 639, 641, 642, 643, 644, 645, 646, 647, 648, 649, 650, 651, 652, 653, 654, 655, 656, 657, 658, 659, 660, 661, 662, 663, 664, 665, 666, 667, 668, 669, 670, 671, 672, 673, 674, 675, 676, 677, 678, 679, 680, 681, 682, 683, 684, 685, 686, 687, 688, 689, 690, 691, 692, 693, 694, 695, 696, 697, 698, 699, 700, 701, 702, 703, 704, 705, 706, 707, 708, 709, 710, 711, 712, 713, 714, 715, 716, 717, 718, 719, 720, 721, 722, 723, 724, 725, 726, 727, 728, 729, 730, 731, 732, 733, 734, 735, 736, 737, 738, 739, 740, 741, 742, 743, 744, 745, 746, 747, 748, 749, 750, 751, 752, 753, 754, 755, 756, 757, 758, 759, 760, 761, 762, 763, 764, 765, 766, 767, 768, 769, 770, 771, 772, 773, 774, 775, 776, 777, 778, 779, 780, 781, 782, 783, 784, 785, 786, 787, 788, 789, 790, 791, 792, 793, 794, 795, 796, 797, 798, 799, 800, 801, 802, 803, 804, 805, 806, 807, 808, 809, 810, 811, 812, 813, 814, 815, 816, 817, 818, 819, 820, 821, 822, 823, 824, 825, 826, 827, 828, 829, 830, 831, 832, 833, 834, 835, 836, 837, 838, 839, 840, 841, 842, 843, 844, 845, 846, 847, 848, 849, 850, 851, 852, 853, 854, 855, 856, 857, 858, 859, 860, 861, 862, 863, 864, 865, 866, 867, 868, 869, 870, 871, 872, 873, 874, 875, 876, 877, 878, 879, 880, 881, 882, 883, 884, 885, 886, 887, 888, 889, 890, 891, 892, 893, 894, 895, 896, 897, 898, 899, 900, 901, 902, 903, 904, 905, 906, 907, 908, 909, 910, 911, 912, 913, 914, 915, 916, 917, 918, 919, 920, 921, 922, 923, 924, 925, 926, 927, 928, 929 are all prime. Hence, the highest power of 3 occurring in it is 1. To illustrate, let's compare the prime nature of N with the factorization. 1.7^1 * 2^(6) * 3.1 * 5^(6) * 7.1 * 11.1 * 13.1 * 17.1 * 19.1 * 23.1 * 29.1 * 31.1 * 37.1 * 41.1 * 43.1 * 47.1 * 53.1 * 59.1 * 61.1 * 67.1 * 71.1 * 73.1 * 79.1 * 83.1 * 89.1 * 91.1. Now, that 3 never divides 7 or 41 in this arragemenr, the highest existing copy of 3 is 1. Thus, k = 1. I hope that clears everything out!

The two-digit integers from 19 to 92 are written consecutively to form the large integer N = 192021 · · · 909192. Suppose that 3^k is the highest power of 3 that is a factor of N. What is k?

To find the highest power of 3 that divides N, we need to count the number of times 3 appears as a factor in the product of all the two-digit integers from 19 to 92.

To do this, we can count the number of multiples of 3, 9, 27, and so on, since each of these numbers contributes one factor of 3. We stop once we reach a number that is greater than 92, since those numbers won't be part of our product.

Here's how we can do this:

* There are 24 multiples of 3 from 19 to 92, namely 21, 24, ..., 90, 93 (but we stop at 90).
* There are 8 multiples of 9 from 19 to 92, namely 27, 36, ..., 81, 90.
* There are 2 multiples of 27 from 19 to 92, namely 54 and 81.
* There are no multiples of 81 from 19 to 92.

So in total, we have 24 + 8 + 2 = 34 factors of 3 in our product.

Therefore, k = 34.
