b)5*(4+3*7)-2*{5+2*[10-3*(14-3*4)]}
c){30+10*[207-6*(28+28:7)]}:10-1
d)300-6*[(2^2+2*13)-3*3^2+17]​

Answer 1

Răspuns:

a)195-6*(30-27+17)

=195-6*20

=195-120

=75

b) 5*25-2*[5+2*(10-3*2)]

=5*25-2*(5+2*4)

=5*25-2*13

=125-26

=99

c) [30+10*(207-6*32)]:10-1

=(30+10*15): 10-1

=30+150 : 10-1

= 180:9

=20

d)300-6*[(2^2+2×13)-3*3^2+17]=

=300-6*(4+26-3×9+17)

=300-6*( 4+26-27+17)

=300- 6*20

=300-120

=180
