`(9y+1/(4y))^3`

Solve the equation and verify your answer: (y-(7-8y))/(9y-(3+4y))=2/3

Solve the equation and verify your answer: (y-(7-8y))/(9y-(3+4y))=2/3

If y=3^((1)/(3))+3, then y^(3)-9y^(2)+27y=

The value of {(x-y)^3+(y-z)^3+(z-x)^3}/{9(x-y)(y-z)(z-x)} (1) 0 (2) 1/9 (3) 1/3 (4) 1

Solve: (9-3y)/(1-9y)=8/5
