Răspuns:

a) {[(45•5+175)•2-300]•15-75•4}•4-6795

{[(225+175)•2-300]•15-75•4}•4-6795

{[400•2-300]•15-75•4}•4-6795

{[800-300]•15-75•4}•4-6795

{500•15-75•4}•4-6795

{7500-300}•4-6795

7200•4-6795

28.800-6795=22005

b)5•{25•8-[221-(56•4-213)•11]•2}+597

5•{25•8-[221-(224-213)•11}•2}+597

5•{25•8-[221-11•11}•2}+597

5•{25•8-[221-121}•2}+597

5•{25•8-100•2}+597

5•{200-200}+597

5•0+597=
