18 multiplied by 4 is 72.
(x^2 - 6x + 18)(x^2 + 6x + 18)
2 x 18 2 x4
X4.

sqrt(x4) = x4/2 = x2

To demonstrate that the function x3 is in the set o(x4), you can show that the limit of x3 divided by x4 as x approaches infinity is equal to 0. This indicates that x3 grows slower than x4, making it a member of the set o(x4).
(x2 + y2)(x + y)(x - y) = x4 - y4.
x times x times x times x = x4
N = x4 x8 = x4+4 = (x4)2 = N2
