B){15+2×[4+3×(120×4+9×3-2-2-2)]-4}×10
C)120+3×{2×3×40+7×[9×2-2×(3×6-3-6)+10]-40}-9
D)13×{24+6×[24-3×(8×4-31)]-150}+402
E)42+18×{5+3×[21+2×(529-8×48)-12×2]-9}-41
F)2012-{2012-{2012-{2012-{2012-[2012-(2012-2011)]}}}}.Dau COROANA!!!!!!HELP!!!!!!

Answer 1

A) 3+5*{82+3*[21+4*(24-9)]}
=3+5*[82+3*(21+4*15)]
=3+5*[82+3*(21+60)]
=3+5*(82+3*81)
=3+5*(82+243)
=3+5*325
=3+1625
=1628


B) {15+2*[4+3*(120*4+9*3-2-2-2)]-4}*10
= {15+2*[4+3*(480+27-2-2-2)]-4}*10
={15+2*[4+3*(507-2-2-2)]-4}*10
={15+2*(4+3*501)-4*10
=[15+2*(4+1503)-4*10
=15+2*1507-4*10
=15+3014-40
=3029-40
=2989

Cam atat am putut scrie. Nu prea mai am timp. Sper sa imi dai coroana :D
