    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

    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
