Answer:
[tex]x^{-28}*7^{-56}[/tex]
Step-by-step explanation:
Firstly, you need to know that raising a fraction to a power raises both the top and the bottom to that power.
Second, a negative power on the top and bottom flips the fraction
Last, raising a power to a power multiplies the powers
So, [tex]\frac{7^{-8^{7}}}{x^{4^7}}[/tex]=[tex]\frac{7^{-56}}{x^{28}}[/tex]=[tex]\frac{1}{x^{28}*7^{56}}[/tex]=[tex]x^{-28}*7^{-56}[/tex]
