When you have the power multiplied to another power you have to multiply
so
(a^3)^3 - (b^3)^3 = a^9 - b^9

A is correct.

B is incorrect because when you multiply the exponents you get a^18 - b^18

C is incorrect because when you distribute the 2 you get a^6 - b^6

D is correct too

If p varies inversely with q, and p = 2 when q = 1, find the<br>equation that relates p and q.

NeTakaya

Answer:

p = $\frac{2}{q}$

Step-by-step explanation:

Given that p varies inversely with q then the equation relating them is

p = $\frac{k}{q}$ ← k is the constant of variation

To find k use the condition p = 2 when q = 1, thus

k = pq = 2 × 1 = 2

p = $\frac{2}{q}$ ← equation of variation
