se dau nr:a=214,b=2,c=325 Sa se afle
a) axb+c-bx[(a+bxc)-(a+c)]:5=

b) c+bxa+bx[(c-a)xb-a]=​

Answer 1

Răspuns:

214×2+325-2×[(214+2×325)-(214+325)]:5=

=428+325-2×(864-539)=

=753-2×325=

=753-650=103

325+2×214+2×[(325-214)×2-214]

=325+428+2×(111×2-214)

=753+2×(222-214)=

=753+2×8

=753+16

=761
