3 si 4 repedeeeew☆☆☆☆​

Answer 1

3. 112(1×53+32×1-1+45×84)=

= 112(53+32-1+45×84)

= 112(53+32-1+3780)

= 112(85-1+3780)

= 112(84+3780)

= 112×3864

= 432768

4. Notam numerele a si b

1) a-b=51

2)a÷b=2 rest 20 => a=b×2+20

b×2+20-b=51

2b+20-b=51

b+20=51

b=51-20 => b=31

b=31 => a=51+31

a=82
