you could multiply 84 by 10 = 840 then multiply 84 by 2 = 168 add these two numbers = 1008
(42,2)(28,3)(21,4)(14,6)(12,7)
9.165151389911680013176094387456 Solution: n * n = 84 n ^2 = 84 n = sqrt (84) n = 9.165151389911680013176094387456 check: 9.165151389911680013176094387456^2 = 84 = true! If you don't mean the square root of 84, then there are a number of numbers you can multiply to get 84, such as these: 42 * 2 28 * 3 21 * 4 14 * 6 7 * 12
