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
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
