Answer 2

Answer:

$\bold{ \huge{481}}$

Step-by-step explanation:

$x = 4 \: \: \: \: \: y = 3 \\ {x}^{4} = {4}^{4} \\ = 4 \times 4 \times 4 \times 4 \\ = 256 \\ {x}^{2} {y}^{2} = {(4)}^{2} {(3)}^{2} \\ = 16 \times 9 \\ {x}^{2} {y}^{2} = 144 \\ {y}^{4} = {(3)}^{4} \\ = 3 \times 3 \times 3 \times 3 \\ = 81 \\ now \: \\ {x}^{4} + {x}^{2} {y}^{2} + {y}^{4} = 256 + 144 + 81 \\ \: \: \: \: \: \: \: = 481$
