Answer 2

Answer:

[(81/16)^-3/4×[(25/9)^-3/2÷(5/2)^-3]=(3^4/^2^4)^-3/4×[(5^2/3^2)^-3/2÷(5/2)^-3]

=[(3/2)^4]^-3/4×[(5/3)^2]^-3/2÷[(5/2)^-3]

=(3/2)^4×-3/4×[(5/3)^2×-3/2÷(5/2)^-3]

=(3/2)^3×[(5/3)^-3÷(5/2)^-3]

= (2/3)^3×[(5/3)^-3×(5/2)-3]

=2^3/3^3×[3^3/5^3÷2^3/5^3]

=2^3/3^3×[3^3/5^3×5^3/5^3]

= 1,Answer
