Answer 1

[Ngô Thị Hương Giang]

160-(2^3.5^2-6.25)= 160-(8.25-150)=160-50=110

4.5^2-32.2^4= 4.25 - 32.16= 100-512=-412

5871:[928-(247-82).5]=5871:[(928-165).5=5871: ( 763.5)=5871:103=57

777:7+1331:11^3 = 111+1331:1331 = 111+1=112

17.85+15.17-120=17(85+15)-120=17.100-120=1700-120=1580

15.141+59.15=15(141+59)=15.200=3000

20-[30-(5-1)^2]=20-[30-4^2]=20-(30-16)=20-11=9

37-11.3.(24-23)+22.10= 37-33.1+220=37-253=-216
