132 - (236 - 432 - 576) = 132 - (-196 - 576) = 132 - (-772) = 904
55 - [132 - 2 x (45 - 42)2] + 7 = 55 - (132 - 2 x 32) + 7 = 55 - (132 - 2 x 9) + 7 = 55 - (132 - 18) + 7 = 55 - 114 + 7 = -52
Hoc tot!!!
132-(236-432-576)=132-236+432+576=-104+432+576=328+576=904
55-[132-2(45-42)2]+7
= 55-[132-2*32]+7
= 55-[132-2*9]+7
= 55-[132-18]+7
= 55-114+7=-52
(Chúc học tốt nha :) :) )
