Answer:

C

Step-by-step explanation:

Given that Q varies inversely as the square of p then the equation relating them is

Q = \frac{k}{p^2} ← k is the constant of variation

To find k use the condition Q = 36 when p = 7

k = Qp² = 36 × 7² = 36 × 49 = 1764

Q = \frac{1764}{p^2} ← equation of variation

When p = 6, then

Q = \frac{1764}{6^2} = \frac{1764}{36} = 49 → C

Exponents

9^3 can be rewritten as
