    y2-x4

    to solve this u need to place the variables for the given value

    y= 9

    x=2

    (9)2-(2)4

    9 times 2 is 18

    2 times 4 is 8

    18-8=10

    or if it is

    y^2-x^4

    9^2- (2)^4

    9^2=81

    2^4=16

    81-16 = 65

    Answer:

    Not sure how the question goes.

    Step-by-step explanation:

    2Y – 4X

    2(9) – 4(2) = 18 – 8 = 10

    Or

    Y^2 – X^4

    (9)^2 – (2)^4 = 81 – 16 = 65
