Answer:
[tex]\huge\boxed{7^{x-y}}[/tex]
Step-by-step explanation:
We can use basic exponent rules to simplify this expression.
We know that [tex]a^b \div a^c = a^{b-c}[/tex].
Since we have the same base (7) and different exponents (x, y), we can subtract the exponents and raise the base to that power.
[tex]7^{x-y}[/tex]
