4^-8 = 1/(4^8)

(4^6) x (1/4^8) = (4^6)/(4^8)

Simplify. Note that when dividing with powers, subtract the powers (if the base is the same number)

(4^6)/(4^8) = 4^(6 - 8)

4^(6 - 8) = 4^(-2)

4^(-2) = 1/(4^2)

1/(4²) = 1/16

1/16 is your answer

Answer:


\huge\boxed{4^(-2)}

Explanation:

If we have the expression
4^6 \cdot 4^(-8), our goal is to simplify it.

Using exponent rules, we know that
a^b \cdot a^c = a^(b+c).

Therefore, we can add our exponents (since we have the same base, 4) to get our simplified expression.


6 + -8

Adding a negative is the same as subtracting a positive.


6 - 8 = -2

Now we raise 4 to that power.


4^(-2)

Hope this helped!
