4*6=24; 14* 16=224; 24*26=624; 34*36= 1224. The law stipulates that:

n4 * N6 =(N * N+N)* 100+24 =[N *(N+ 1)* 100]+24

First, the mantissa is 24, and the first hundred digits of 24 start with the product of two tens, and then add ten digits, as follows

Ten digits are 0: (0 * 0+0) * 100+24 = 24, 4 * 6 = 24;

The ten digits are 1, (1*1+) *100+24 = 224,14 *16 = 224;

Ten digits are 2: (2 * 2+2) * 100+24 = 624, 24 * 26 = 624;

The ten digits are 3: (3 * 3+3) *100+24 =1224, 34*36= 1224.

The ten digits are 4: (4 * 4+4) * 100+24 = 2024, 44*46=2024.

The number of decimal places is 5: (5 * 5+5) * 100+24 = 3024, 54*56=3024.

The number of decimal places is 6: (6 * 6+6) * 100+24 = 4224, 64*66=4224.

The ten digits are 7: (7 * 7+7) * 100+24 = 5624, 74*76=5624.

The number of decimal places is 8: (8 * 8+8) * 100+24 = 7224, 84*86=7224.

The ten digits are 9: (9 * 9+9) * 100+24 = 9024, 94*96=9024.

These ten digits are10: (10 *10+10) *100+24 =11024,/kloc-

These ten digits are11:(11*1) *100+24 =13224.

. . . . . . The analogy is as follows

The ten digits are 77: (77 * 77+77) *100+24 = 600624, 774*776=600624.
