To write four 5s and make them represent 56 you need to write 55 + 5/5. When worked out it becomes 55 + 1 (5/5=1) which equals 56.
55 + 5/5
4 = 20 / 5
by dividing
One possibility is 55 + 5*5 = 55 + 25 = 80
there are four 5s each one a different suit ( hearts, spades, diamonds, clubs)
21 5s
5s
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
It is 5s + 4d.
5s-r
-6s+10 = -5s 5s-6s = -10 -s = -10 s = 10
5S in Total Quality Management (TQM) is a systematic approach to workplace organization. 5S is about efficiency, competitiveness and survival.
