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

Prime factors of 84 are 2 x 2 x 3 x 7. There are not four different prime numbers that produce a product of 84.

Of course the primes cannot be unique since 2x3x5x7=210>84.The answer is 2x2x3x7.

There are lots of solutions for that. Here is one:1 x 84

84 = 1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, 7 x 12

You take the number and multiply it by itself and then the question becomes a simple multiplication problem.

because when you multiply 2x2 it =4 then you multiply 4x3=12 then you multiply 12x7=wich you will have your answer 84!

If you mean prime factors then: 2, 2, 7, 3. Multiply those numbers by each other in various combinations to find all the factors of 84.
