Thanks Kendall!!!
I think it is 3w
The formula is wrong. It should be term(n) = ( n^3 + 23(n) - 8 ) / 2

For n=5 l=2 we get 5d, which has 5 orbitals and added s and p (1 and 3) we get 9.
Thank you Ms. Sue
Actually I didn't know that formula haha. Thanks!
I don't agree Anonymous. To solve 2nd degrees equations (aka find the roots of a trinomial function), you have first to put it to this form : ax² + bx + c = 0 (where a, b and c are reals) Then you have to calculate its discriminant (its delta) : Δ = b²
Simple equation : X = -sqrt(2)/sec(1/4) = -sqrt(2)*cos(1/4) It's not a round value.
For the first one : You put X = x² Then you have (variable change) : X² - 6X + 8 = 0 And you use common tools to solve that (use delta). You find X = 2 or X = 4. You have x² = X, so x = sqrt(X) or x = -sqrt(X). Here, the solutions are sqrt(2), -sqrt(2),
