Answer:
A
Step-by-step explanation:
[tex]p(n)=7n^3,\,p(n)=56\implies 7n^3=56\implies n^3=8\implies \boxed{n=2}[/tex]
Therefore, the answer is A.
Answer:
A) 2
Step-by-step explanation:
p(n) = 7n^3
Let p(n) = 56
56 = 7n^3
Divide each side by 7.
56/7 = 7/7 n^3
8 = n^3
Take the cube root of each side.
∛8 = ∛n^3
2 = n
