    A is rational (A=432)

    B is irrational (B=411.6862 ...) (non repeating)

    C is rational (C=3807)

    D is irrational (D=299.1061 ...)

    these are the answers but im not sure how to tell without simplifying for this

    √8 will never be rational

    √9 is a whole number therefore it will come out rational in these equations
