Answer:
a) 57800
b) 667200
c) 501486
d) 31936
Step-by-step explanation:
a) 578×27+578×73
= 578(27+73)
= 578×100 = 57800
b) 6672×134-6672×34
= 6672×(134-34)
= 6672×100 = 667200
c) 498×1007
= 498×(1000+7)
= 498×1000+498×7
= 498000+3486 = 501486
d) 998×32
= 32×(1000-2)
= 32×1000-32×2
= 32000-64
= 31936
