Question

Calculati tinand cont de ordinea efectuarii operatiilor:
a) 2x(1020:85+205:[33x18-(50x10+23x4)]+1343:17-262
b) Cmmmc a 2 nr nat a si b este 180, iar produsul celor 2 nr este 1620. Calculati cmmdc.

Answer 1

Răspuns:

a) 2x(1020:85+205:[33x18-(50x10+23x4)]+1343:17-262=

2×(12+205:[594-(500+92)]+79-262=

2×(12+205:[(594-592)]+79-262=

2×(12+205:2)+79-262=

2×(12+102,5)+79-262=

2×114,5+79-262=

229+79-262=

308-262=

46
