Step-by-step explanation:
we have 8 equally "heavy" batches.
one weighs 3.9 × 10^-10 g
so, the total sample then weighed
8 × 3.9 × 10^-10 = 31.2 × 10^-10 = 3.12 × 10^-9 g
Asnwer: C

Multiplicity of a root means, is there that many times.
The value of a2 will be I dont care
Answer:
not proportional
Step-by-step explanation:
If it is proportional y/x = constant
