3 ) Efectuează .a ) 6 × 14 - 2 × ( 40-27 :3 ). b) 1 012 - 5 × ( 9 : 3 × 3 + 202 : 2 ) . c ) (6×14-2)×(40- 27: 3 ) d) ( 2×3 la puterea 2 +3 × 2 la puterea 2 ) :6+ 5 la puterea 2 : 5 +10 la puterea 2.​

Answer 1

Răspuns:

a) 6 * 14 -2 * (40-27:3)=

6*14 -2 * (40-9)=

6*14 -2 * 31=

84- 32= 52

b)1012 - 5* (9:3 *3+202:2)=

1012- 5* (3 *3+ 202:2)=

1012 -5* (9+101)=

1012- 5* 110=

1012- 550=462=

c) (6*14-2)*(40-27:3)=

(84-2)*(40-9)=

82*31=2542

d) (2*3²+3*2²): 6+5²:5+10²=

(2*9+ 3*4):6+25:5+100=

(18+12):6+5+100=

30:6+5+100=

5+5+100=110
