When it begins to multiply by using letters that get you quickly realize that AC sometimes ending in a 7, a * c = 7,17,27,37,47,57,67,77 means .... Only 2 of these that are the product of 2 1 figures. 7 = 7 * 1 and 27 = 9 * 3.
If A and C = 9 a.m. to 3 p.m., the smallest possible product is, if b = 0 309 * 903 = 279027, which is much larger than 100,147, so that A and C are 3 p.m. to 9 p.m.. They should be 1 and 7
We have (if it is 7 or C, because 1B7 * 7B1 * 7B1 = 1B7)
1B7

Is written in good mathematical notation
(107 b 10) (701 10 b) = 100147
75.007 8.080 b 100 b ^ 2 = 100147
100 B ^ 2 = 8080 B 25,140
100 B ^ 2 8080 = 188356 B 163,216
(10b 404) ^ 2 = 434 ^ 2
10b, 404 = 434 or 10 b, 404 =- 432
10b = 30 or 10 b = -836
b = 3, b =- 8.36, but this can not be a number, and raises the
You can also perform this step, the less mathematical selection of a number of B and whetherWork. Not long, because there are not many opportunities.
137 * 731 = 100147
751 x 157 = 117907.
591 x 195 = 115245.
581 x 185 = 107485.
(571 x 175 = 99925.
You can use this 2nd place
651 x 156 = 101556).
Sorry, I can not work. : (
