The simplified expression is 40 - 12s
16s + 4s = 20s
(4s + 1)(4s + 1) or (4s + 1)2
since A=4S then S=A/4 A is not 4S. The perimeter P is 4S. The area is S multiplied by S or S squared. therefore the side of a square is the square root of the area.

The orbital designations 3f and 2d are invalid. The letter "f" is not used to designate orbitals, and the numbers in the designation should follow a specific order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, etc.
equivalent fraction of 3/4 = 6/8
If that is l and not 1 then it is 3.5l+2s when simplified
3f can not exist by the Aufbau principle, quantum mechanics and Hunds rules. In level one there is only 1s In level 2 there is 2s and 2p In level 3 there is 3s, 3p and 3d Only in level 4 and beyond is there an f shell. In level 4 there is 4s, 4p, 4d and 4f. The 4f can hold up to 14 electrons.
The simplified expression is 40 - 12s
.444444444444444444444444 (the 4s go on forever)
no 5/6s is larger than 3/4s
The s orbital is present in all valid principal quantum number shells.The p orbital is present in n = 2 and higher.The d orbital is present in n = 3 and higher.The f orbital is present in n = 4 and higher.So the invalid ones are b (there are no 2d orbitals) and c (there are no 3f orbitals). 4s and 3p are perfectly legitimate.
It can't be factored because the discriminant of the given quadratic expression is less than zero
16s + 4s = 20s
16s + 4s = 20s
