Explicație pas cu pas:
A×(B+C)=11×8=888
2A+3(B+C)=2×11+3×8=22+24=46C10A+9(B+C)
Răspuns:
a) a×b+a×c= 11(b+c)=11×8=88
b) 2a+3b+3c= 2×11+3(b+c)=22+3×8=22+24=46
c) 10a+9b+9c= 10×11+9(b+c)=110+9×8=110+72=182
d) ab+ac+25=11(b+c)+25=11×8+25=88+25=113
e) ab+ac-34=11(b+c)-34=88-34=54
f)7b+7c+9a= 7(b+c)+9×11=7×8+99=56+99=155
g) 11b+11c-6a= 11(b+c)-6×11=11×8-66=88-66=22
h) 3a-3b-3c= 3×11-3×8=33-24=9
i) 11b+ac= 11b+11c=11×(b+c)=11×8=88
