Question

What is the value of y2 – x4 when y = 9 and 2 =2?

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

Answer 2

Not sure how the question goes.

Explanation:

2Y - 4X

2(9) - 4(2) = 18 - 8 = 10

Or

Y^2 - X^4

(9)^2 - (2)^4 = 81 - 16 = 65
