OK so basically when you are dividing in this type of problem you are going to subtract so a^ 3 - a^6 is a ^ -3 and for b you are going to subtract as well so b^ 6 - b ^ 3 is b^ 3 so your final answer will result in a^-3 - b ^ 3 hoped that helped :)
What you need to do is subtract the exponents because you are multiplying a³ b⁶ ____ a⁶ b³ = a⁻³ b ³ But you can't have a negative exponent so you need to put in in the denominator b³ ____ <---- that's your answer a³
