Question

answer fast it's urgent

if x/y = (2/5)² divide (2/5)^0 then find (x/y)²

answer with steps ​

Answer 1

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

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

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