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
