(2÷5)^9×y=(2÷5)^5
(2^9÷5^9)×y=(2^5÷5^5
y=(2^5÷5^5)×(5^9×2^9)
y=(5^4÷2^4)
y=(5÷2)^4
verification
(2÷5)^9×y=(2÷5)^5
(2÷5)^9×(5÷2)^4=(2÷5)^5
(2÷5)^5=(2÷5)^5
hence verified
(2^9÷5^9)×y=(2^5÷5^5
y=(2^5÷5^5)×(5^9×2^9)
y=(5^4÷2^4)
y=(5÷2)^4
verification
(2÷5)^9×y=(2÷5)^5
(2÷5)^9×(5÷2)^4=(2÷5)^5
(2÷5)^5=(2÷5)^5
hence verified

(2/5)^9 × y = (2/5)^5
=> y = (2/5)^5 ÷ (2/5)^9
=> y = (2/5)^-4 = (5/2)^4
