The answer depends on what n represents.
C represents carbon, O represents oxygen, N represents nitrogen, and H represents hydrogen.
N represents 100
n usually represents and unknown variable
Hg represents mercury, Au represents gold, As represents arsenic, Sr represents strontium, N represents nitrogen, and Gd represents gadolinium.
25n
It should be: n-10
Whats n+8
4*n(n+1)
Not necessarily. A represents anything which you define it to be.
N represents Nitrogen.....
n ∑(f(x)/n) x = 0 Where f(x) represents the xth element in the set you're averaging, and n represents the number of elements in that set.
