Answer:
The two complex numbers are 
Explanation:
We have to form two complex numbers of the form

such that and d are irrational numbers and b and c are rational numbers.
We know that
are irrational numbers.
5 and 6 are rational numbers.
We put

Thus, the two complex numbers are: 
They are atoms like hydrogen oxygen or nitrogen
MM Zn(NO₃)₂ = 189.36 g/mol
mass 1 mol Zn(NO₃)₂ = 189.36 g
mass hydrate = 100 / 63.67 x 189.36 = 297.409 g
mass 1 mol hydrate = 297.409 g
MM hydrate = 297.409 g/mol
MM hydrate = MM Zn(NO₃)₂ + MM xH₂O
297.409 = 189.36 + x(18)
x = 6
Your answer would be A for your homework
