Answer 1

Răspuns:

$650*6-900: 3 +268=3900-300+268=3868\\\\27*(9*309 + 3452 - 236*8) =27*(2781+3452-1888)=27*4345=117315\\\\(737 + 6a) - 16*13= 553\\\\(737+6a)-208=553\\\\6a=553+208-737\\\\a=24:6= > a=4$

650x6-900:3+268=3900-300+268=3600+268=3868

27x(9x309+3452-236x8)=27x(2781+3452-1888)

=27x(6233-1888)

=27x4345=117315
