Answer 1

Answer:

$x^{-28}*7^{-56}$

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, $\frac{7^{-8^{7}}}{x^{4^7}}$=$\frac{7^{-56}}{x^{28}}$=$\frac{1}{x^{28}*7^{56}}$=$x^{-28}*7^{-56}$
