All of the numbers are "calculator words", meaning that rotating 180 degrees makes them look like they're spelling a word. However, they each have one blank at the decimal point which can be filled in with a letter to make an answer to the clue. Here are the clue answers (with the missing letter in brackets) and the rotated numbers:





The missing letters from each group spell out TSWIFTSONG, THESES, PLANETS, and SENATORS. These correspond to the numbers 22, 95, 8, and 100. Plugging those into the final equation yields 22*95*(2^8+1)/100 = 5371.3, which rotates to E?ILES. The only common English word with this pattern is EXILES.
