Answer:
A and D
Step-by-step explanation:
1/5 is the same as 5^(-1),
so (1/5)^4=5^(-4)
as we know,
when you multiply the bases, you add the exponents
when you divide the bases, you subtract the exponents
when you simplify a term with and exponent with another exponent, you multiply them
so,
a)
(5^(-2))^2=5^(-2*2)=5^(-4)
b)
(5^(-4))^0=5^(-4*0)=5^0
c)
5^(1)/5^(4)=5^(1-4)=5^(-3)
d)
5^(2)*5^(-6)=5^(2-6)=5^(-4)
The two answers are A and D
