#### Answer

$$15a^{6k}+10a^{4k}-20a^{2k}$$

#### Work Step by Step

In order to divide by a polynomial, we first factor the numerator. Next, we look for common terms in the numerator and the denominator. Finally, we cancel out common terms to get the final answer. Doing this, we find: $$\frac{45a^{8k}+30a^{6k}-60a^{4k}}{3a^{2k}} \\ \frac{15a^{4k}\left(3a^{4k}+2a^{2k}-4\right)}{3a^{2k}}\\ 5a^{2k}\left(3a^{4k}+2a^{2k}-4\right) \\ 15a^{6k}+10a^{4k}-20a^{2k}$$
