Answer 1

6.
a) {[1200•(8-8) +36]-3096: 387}:2 la puterea 2 =
= [(1200•0+36) -3096: 387): 2 la puterea 2=
= (36-8) : 2 la puterea 2 = 28: 4= 4,2

b) 26+5• [4+(40+8•16•25: 10-4•25)•5]+11=
26+5•[4+(30+320-100) •5]+11=
26+5•(4+450•5) +11=26+5•(4+2250) +11=
26+5•2254+11=26+11 270 + 11 = 11 307

c) 2•(9•16: 3: 16) -882: 49=
=2•3-882: 49=6-18= -12

d) [(4•7•2: 14-27: 27): 1+524: 131]•6-36=
=(3: 1+4) •6-36=(3+4) • 6 - 36= 7•6-36=42-36=6

e)1600:4[3•70-(90-9•8•5•3: 12): 75•4+95•2]: 12=
=1600: 4:[3•70-(90-90): 75•4+95•2]: 12=
=1600: 4 :(3•70-0: 75•4+95•2): 12=
=1600: 4: 400: 12=0, 08
