Answer:
The correct option is D.
Explanation:
x2018y2017 = 1/2
x2016y2019 = 8
Divide the two equations,
x2/y2 = 1/16
x/y = 1/4
y = 4x
So, x2016(4x)2019 = 8
x4035 × 24038 = 23
x = 1/2
y = 2
Hence, x2 + y3 = 1/4 + 8
= 33/4

Answer:
Explanation:
20182017=12…..(1)
and 20162019=8…..(2)
Dividing (1) by (2), 22=116
=14 i.e. =±14
(±14)20182017=12
4035=24035
=2
Therefore, =±14=±12
Hence, 2+3=14+8=334
