1/55 a)16+16x2 b)9+3x457 c)2x(1400-54) d)6x[3+3x(4+4x225)] 4/56| Calculati folosind metoda factorului comun
a)3x7+3x15+3x13
b)33x117+33x15x133
c)201x327-201x307+201x23

Răspuns :

a) =16(1+2)=16x3=48
b)= 3(3+457)=3x460=1380
c)  =2x1346=2692
d)  =6x[3+3x4 x(1+225)]=6x3x[1+4x226]=18x(1+904)=18x905=16290

a)  =3x(7+15+13)=3x35=105
b) =33x(117+15x133)=33x(117+1995)=33x2112=69696
c)  =201x(327-307+23)=201x43=8643
