Question

14 si 18 pls dau 20 puncte si coroana daca e corect!!

Answer 1

14.
x=11a+3
x=10b+2

x+8=11a+3+8
x+8=10b+2+8

x+8=11a+11=M(11)
x+8=10b+10=M(10)
x+8=M(11×10)=M(110)
100<M(110)<999    
multipli de 110 cuprinsi intre 100 si 999 sunt:
110,220,330,440,550,660,770 ,880,990
numerele cautate sunt x=M(110)-8
x={102,212,322,432,542,652,762,872,982}


18.
x=M(11)+8
x=M(12)+9
x=M(8)+5

x+3=M(11)+8+3
x+3=M(12)+9+3
x+3=M(8)+5+3

x+3=M(11)+11=M(11)
x+3=M(12)+12=M(12)
x+3=M(8)+8=M(8)
11=11
12=2²×3
8=2³
cmmmc=2³×3×11=264
x+3=264
x=264-3=261
