Answer 1

20+2×{32:8+4×[20+4×(800:5-36:2)]}=
=20+2×{4+4×[20+4×(160-18)]}=
=20+2×[4+4×(20+4×142)]=
=20+2×[4+4×(20+568)]=
=20+2×(4+4×588)=
=20+2×(4+2352)=
=20+2×2356=
=20+4712=
=4732
150+{450:5+25:5×[975-(50:5+3)×75]}×2=
=150+{90+5×[975-(10+3)×75]}×2=
=150+[90+5×(975-13×75)]×2=
=150+[90+5×(975-975)]×2=
=150+(90+5×0)×2=
=150+(90+0)×2=
=150+90×2=
=150+180=
=330
288+819:9+4×[20+6×(245:5-246:6)]=
=288+91+4×[20+6×(49-41)]=
=288+91+4×(20+6×8)=
=288+91+4×(20+48)=
=288+91+4×68=
=288+91+272=
=379+272=
=651
56+5×{64:8+4×[40+7×(300:5-72:2)]}=
=56+5×{8+4×[40+7×(60-36)]}=
=56+5×[8+4×(40+7×24)]=
=56+5×[8+4×(40+168)]=
=56+5×(8+4×208)=
=56+5×(8+832)=
=56+5×840=
=56+4200=
=4256
