Question

please tell me the answer in process ​

Answer 1

Answer:

16/625

Step-by-step explanation:

Answer 2

$\rm{(x/y)^2=[(2/5)^2 \div (2/5)^0]^2}\longrightarrow\rm{(x/y)^2=[4/25 \div 1]^2}$

$\rm{(x/y)^2=[(2/5)^2 \div (2/5)^0]^2}\longrightarrow\rm{(x/y)^2=[4/25 \times 1/1]^2}$

$\rm{(x/y)^2=[(2/5)^2 \div (2/5)^0]^2}\longrightarrow\rm{(x/y)^2=(4/25)^2=16/625}$
