Further expressions involving division law with variable bases

We've learnt about the division law which states:

$\frac{a^x}{a^y}=a^{x-y}$axay​=ax−y

Now we are going to apply this rule to questions that also have integer coefficients and more than one unknown value. We are also going to look at expressions that involve the power law. It's the same principle - just remember you can only apply the division rule to terms with like bases (and, of course, we can simplify numeric expressions as normal).
