The real solutions are -5, -4, 4, 5. There are no complex solutions.
The equation ...
... x^4 -41x^2 +400 = 0
can be factored as ...
... (x^2 -16)(x^2 -25) = 0
... (x -4)(x +4)(x -5)(x +5) = 0
So, all roots are real and are ...
... x ∈ {-5, -4, 4, 5}
_____
These are the values of x that make the factors zero.
<em>Answer,</em>
100,000,000 > 334,605,925
But, 100,000,000 is smaller that 334,605,952
So, It would be "100,000,000 < 334,605,925"
