Answer 1

Răspuns:

Mod 1

127×(6+2)=127×8=1016

(3+4)×236=7×236=1652

149×(2+5)=149×7=1043

(5+2)×194=7×194=1358

2×(126+121+97)=2×344=688

5×(101+96+202)=5×399=1995

Mod 2

127×(6+2)=127×6+127×2=762+254=1016

(3+4)×236=3×236+4×236=708+944=1652

149×(2+5)=149×2+149×5=298+745=1043

(5+2)×194=5×194+2×194=970+388=1358

2×(126+121+97)=2×126+2×121+2×97=252+242+194=688

5×(101+96+202)=5×101+5×96+5×202=505+480+1010=1995
