Question

verifica egalitatile [(1+2):3+4]×5+6×(2+8):10=31

[2+2+2):2-2]×[(3+3+3):3-3×1]=7

Answer 1

[(1+2):3+4]×5+6×(2+8):10=
=(3:3+4)×5+6×10:10
=(1+4)×5+60:6
=5×5+6
=25+6
=31 A
[(2+2+2):2-2]×[(3+3+3):3-3×1]=
=(6:2-2)×(9:3-3)
=(3-2)×(3-3)
=1×0
=0 F

Answer 2

[(1+2):3+4]x5+6x(2+8):10=31 (3:3+4)x5+6x10:10 (1+4)x5+60:10 5x5+6 25+6 31 Egalitatea aceasta este egala [2+2+2):2-2]x[(3+3+3):3-3x1]=7 [2+2+2):2-2]×[(3+3+3):3-3] [4+2):2-2]×[(6+3):3-3] (6:2-2)×(9:3-3) (3-2)×(3-3) 1×0 0 Egalitatea aceasta este falsa
