35 35X35=1225
35 to the second power is the same as 35x35=1225.
1x5x7x35=35x35=1,225
1360
The answer depends on the units of measure for 35x35. Clearly a room that is 35 feet * 35 feet will be quite different to that measuring 35 inches x 35 yards!
The answer is within the range 352 to 402, that is, it is between 1225 and 1600. If it is a multiple of 17 and has 42 as a factor then then it is also a multiple of 17 x 16 = 272. The only multiple of 272 within the specified number range is 5 x 272 = 1360.
