Chaim Mann · Answer 1

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
