2 8 9 3=10

Answer 1

(3:3)+(3*3)=10          sper ca team ajutat

Answer 2

3 3 3 3=10....=>
3*3+3:3=10......adica......=>9+1=10

4 4 4 4=10...=>
(44-4):4=10.....adica......=>40:4=10.....sau...10=4+√4+4*√4=(44-4):4

2 8 9 3=19...=>
2*8+9:3=19.....adica......=>16+3=19

2 8 9 3=7....=>
2+8-9:3=7.......adica......=>10-3=7

2 8 9 3=10...=>
((2*8)-9)+3=10....adica......=>(16-9)+3=10....=> 7+3=10
