fourteen take away four and then add a four and times by (2 times 4)
how do i make 17 using only 2 4 6 8
5s - 6 = 2s, ie 5s - 2s = 6, ie 3s = 6, ie s = 2
3*3*2*1 = 18 of them.
Twelve of them.
four
8
The answer is 9C4 = 9*8*7*6/(4*3*2*1) = 126 ways.
It is 5s + 4d.
5*4+3+2
Yes: 2 x 2 x 2 + 2!
5/5=1 Keep this for later. so 2 5s used. Then do 5*5=25, so 5 5s used as 25 has a five in it, now do 1 - 25=24.

5s - 6 = 2s, ie 5s - 2s = 6, ie 3s = 6, ie s = 2
5x7=35, then 3-1=2, so 35+2=37
That would be [Kr]4d^2 5s^2 or the long form would be1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 4d^2 5s^2
