(x+y) : (x-y),(x²+y²) : (x+y)², (x²-y²)² : (x⁴-y⁴) find mix ratio or compound ratio |

Answer» the compounded RATIO of the RATIOS (a:b), (c:d) and (e:F) is ACE ;BDF (x+y) : (x-y) , (x²+y²) :(x+y)² : (x^4 -y^4) compounded ratio is
(x+y)(x²+y²)(x²-y²) : (x-y) (x+y)²(x^4 - y^4) = (x+y)[x^4 -y^4 ] : (x-y) (x+y)(x+y) [x^4-y^4] after cancellation = 1:(x-y)(x+y) =1: (x²-y²)
