BY SOLVING WILL FIND OUT THAT X IS 984 AND Y IS 9016.

IMPUTING THIS FIGURES INTO THE EQUATION YOU WILL FIND OUT 1=1

log₁₀x + log₁₀y = log₁₀10000

log₁₀x + log₁₀4² = log₁₀1000

log₁₀ (x × y) = log₁₀10000

log₁₀ (x × 4²) = log₁₀1000

xy = 10000

16x = 1000

1000y/16 = 10000

1000y = 160000

y = 160

Therefore

If you appreciate, please mark as best.
