[" If "(x^(3)+4xy^(2))/(4x^(2)y+y^(3))=(15)/(16)," then "x:y" is "],[[" (A) "2:3," (B) "3:2],[" (C) "4:3," (D) "3:4]]

If (x^(3)+4xy^(2))/(4x^(2)y+y^(3))=15/16 , then find x : y.

If (30x + 2y)/(4x + y) = (16)/(3) , then find x:y.

If (4x^2-3y^2):(2x^2+5y^2)=12:19 then x:y=

If (15x + 16y)/(25x + 4y) = (7)/(6) , then find x:y.

Add : 4x^(2)y, - 3xy^(2), -5xy^(2), 5x^(2)y

If x^(4) +x^(2)y^(2)+y^(4)=21 , and x^(2)+xy+y^(2)=3 then what is the value of 4xy?

{:("Column" A ,, "Column" B), ((3x^(2) - 5)- (2x^(2) - 5 + y^(2)) ,, (a) x^(2) + xy + y^(2)) , (9x^(2) - 16y^(2) ,, (b) 2) , ((x^(3) - y^(3))/(x-y) ,, (c) (9x + 16y) (9x - 16y)) , ("The degree of " (x + 2) (x+3) ,, (d) x^(2) - y^(2)) , (,, (e) 1) , (,, (f) (3x + 4y) (3x - 4y)):}

Simplify : 7x^(3)+8y^(3)-(4x+3y)(16x^(2)-12xy+9y^(2))
