Answer:
-1
Explanation:
-(4^6•4^2)/4^4
When bases are same powers are to be added since the base is same(4) powers will be added
-(4^(6+2))/4^4
-(4^8)/4^4
When the power I in denominator and we shift it to the numerator the power become negative
-(4^4•4^(-4))
When bases are same powers are to be added
-(4^(4-4))
-(4^0)
Whenever the "power" is zero the base becomes one
E.g. a^0=1
So
-(1)
-1
The answer is -1
