Answer:
4x -1530y+7388517.774
Step-by-step explanation:
4x- 45y × 34- -43 +π³÷√9-7889²×-2.488×1/3÷14÷2+83π-3×-3399.3884-10³
= 4x- 45y × 34+43 +π³÷√9-62236321×-2.488×1/3÷14÷2+83π-3×-3399.3884-1000
= 4x- 45y × 34+43 +31.018÷3-62236321×-2.488×1/3÷14÷2+83π-3×-3399.3884-1000
= 4x- 45y × 34+43 +10.34-62236321×-2.488×1/3÷14÷2+83π+13199.652
= 4x- 45y × 34+43 +10.34-62236321×-0.1185+260.752+13199.652
= 4x- 45y × 34+43 +10.34+7375004+260.752+13199.652
= 4x -1530y+7388517.774
