Ex 14 si 15 va rog rpd plssss

Answer 1

14)1.320+[48×23+(340×11-60×5)-235×7]=
=1.320+[48×23+(3.740-300)-235×7]=
=1.320+(48×23+3.400-235×7)=
=1.320+(1.104+3.400-1.645)=
=1.320+(4.504-1.645)=
=1.320+2.859=
=4.179

2.307+{3.702+[270÷3+3×(280×5-3×230)=
=2.307+{3.702+[270÷3+3×(1.400- 690)=
=2.307+[3.702+(270÷3+3× 710)=
=2.307+(3.702+90+2.130)=
=2.307+(3.792+2.130)=
=2.307+5922=
=8229

31.975+200×[8×(1.270-2×350)+2.340÷5]=
=31.975+200×(8×570+2.340÷5)=
=31.975+200×(4.560+468)=
=32.975+200×5.028=
=32.975+1.005.600=
= 1.038.575
